Maybe I'm bored with all the bore relieving or what but after about 9 stroker motors in a row I"m a little "stroked-out". I love strokers but sometimes, somehow it makes it almost too easy to make decent power anymore....you gotta admit the 'turn key' 'Kit' recipie approach has taken at least some of the Hotness out of Hot rodding when almost anybody can do it in a "pick one from column A one from column B" method  So....Show me some old school, wind-em up TIGHT stock stroke horsepower. My first sub 12 pass was in a 340 dart with W2's and a 4 speed some 30 yrs ago; I still love the change in pitch you get only from a +7K small block! Keeping in the street theme show me a combo that will make 500hp with the SMALLEST cam required that'll get there. 500 Crank hp should put a typical A body (no real exotic suspension) into the high 10's pretty easy no matter how many cubes you got. Can't wait to fire up this 341"/318....just ordered my pushrods from Smith brothers after scoring a set of old school 273 rockers. I know it won't make 500 (but it could with a solid cam and more r's) but it should make at least 460 by 6500rpm which should be plenty for an 85" wheelbase! http://www.youtube.com/watch?v=wrB62FSfAoU

For a 340 to make about 500 it needs to make peak power around 7200 and for that you need some really good heads in the 270+ range and a cam in the 255+ @.050 with 1 3/4 headers and an 800+ cfm cam. Solid roller in the .575 range should make a high winding 340 make 500 pretty easy with better torque than a F/T. I've always felt 450 was pretty easy to attain and still be streetable, even with a hydraulic cm and a 6500 redline. i want to see if anybody has ever made a bonafide 500hp with a stock stroke 340 that was Street driven. Darryl.....I'm so tempted to try Goldmemember's solid F/T on this thing and I might just yet....with the wheelbase on this thing I want to "ease into the combo so i'll start with a slightly milder and 500-700 lower RPM cap and see how it goes....hte bottom end is there EASY if I want to turn up the wick

I'll chime in on this. My 360 is .040 over, with forged KB pistons, nominal compression is 12.5. It now has Eagle H-beam rods and very modest porting on iron heads. I'm running a Weiand X-terminator intake, which probably doesn't make quite as much power as, say, a Strip Dominator. The cam is the ancient but effective MP 528 solid, augmented by 1.6 rockers. Nothing fancy for an oil pan. I have 1 5/8 headers, which are probably on the small side. The original, which I blew up, had an ancient set of TRW slugs which were well worked over to remove weight, but were still heavier than the new KB's. With an LD4B intake, that motor made 450 (well, 447, actually) on the dyno. From that, I'd say I'm in the 480+ range right now. Next time around, we'll upgrade to a mild solid roller with similar duration and centerline to this cam, a bit more port work, and different intake. Yeah, I think 500 is within reach without going overboard.

Any more out there?
C'mon small block guys, 500 in an A body should handle 600 in a b, right?
Im curious to see what else pops up since i plan on starting my 340 build in about a year and was hopeing for somewhere along 500 crank HP

Small blocks get no love 
Being mainly a big block guy I sympathize....I'll bet a similar "B" motor thread would probably be 3 pages by now
I guess I don't see why a 500HP 408/416 recipie wouldn't make the same power w/stock stroke, but at a higher RPM, unless the heads didn't have enough CSA to run that high, but I don't see why a 360 couldn't make 500 HP under 7K even with a stock stroke
shortblock: KB107's at 0 deck
heads, I'd think any decently ported eddies, EQ's, RHS's, W2's, or even stock LA 340/360 would do it....something that flows in the 260-280@ .55" of lift should get you there
cam, either a somewhat aggressive solid flat tappet, or street solid roller, or even a hydraulic roller or somewhat aggressive hydraulic flat tappet, if you can control valvetrain harmonics/stability....anything in the 235-260@.050 range should get you there, depending on how good the heads are.
to make 500 HP @ 6500 RPM, you'd need to make ~400 ft-lbs at that RPM. I think that's certainly doable with a 360, and still have it relatively streetable.....
or just take a stock 318/360 magnum and put ~12-15lbs of boost on it

Quick, what's your .450 and .600 lift numbers look like? You've got enough flow at .700 to make ~625 my my "rule of thumb" but guessing you've got in the ballpark of 565 right there...or about as much as I'd want to throw at a cast crank anyway!! That sounds like one BadAzz Munchkin motor!!! S/St3040, That is VERY IMPRESSIVE power at a very low RPM from a short stroke motor, I know you're having to work the average 2500-6500 HP/Torque for the EM format. Like I said earlier with 340's the temptation is too easy for motors that love to rev to just throw the flow and cam to them and let the crank wind up tight to make HP.....so your combo is 'mucho impressivo'....I thinking you had some killer work (epoxy maybe?) in that Victor intake to bring the torque in early and use the HP up by 6500, I would think the smallish cam can only get you so much grunt in the middle without the intake pitching in....  That was the Highest Average per cube contest, wasn't it?

don't remember off hand but they were good, I shift it at 6500 and may even lower it more.

don't know yet, never really had a chance to run it hard when I had it in my sons chally. but it ran 11.20 @ 121 running on 2 bbls of the carb, had the back two off. this was a stock suspension street chally 3500#s. I'll do a whats it gonna run in a week or two when I finish the new challenger. but it's a total different combo. the motor is the same but changed a lot of other stuff.

I just completed assembling a stock stroke 360 .020 with KB107, has eddy magnum heads with the bowls blends and minor cleanup in the ports. Camshaft is a Engle 253/253 @.050 .613 lift with 1.6 rockers, M1 Magnum Single Plane Intake, 750 Holly DP. Compression is calculated to be 11.2 to 1. Quench is .043. Using stock rods that have the beams polished and arp wave lock bolts.
I think it going to be close to the 500 hp figure.

Emarine, that sounds like it would be right around 500, My approach is pretty close to that with my 341" except I've got bowl ported/pinch relieved E-heads, Comp HR 236/242 @.50 .520/.540 on 112 in at 107 (need to spread the torque for obvious reasons) aluminum rods and 10.2:1, I'm looking for ~460 @ maybe 6300 or so, by my calcs that should be pretty close...whatcha think?
You could cam up some 8 to 10* go solid and turn it to 7k and be close to 500 if not more

500 HP will put a 3200 lb. car less than 10.50 @ almost 127 MPH. 3000 lbs.......about 10.20 @ over 129 MPH. 2800 lbs.......9.90s @ over 132 MPH. Just some perspective.

Ya gotta watch that kinda stuff. Waaay back when I was a high schooler, I recall a whompin' fast '66 Biscayne that had a "396" and column shifted TH400. Under the hood, only the headers looked non-stock. Stock valve covers, Edelbrock C-454 was painted orange, juice cam, big Holley, and some dual inlet Chevy air cleaner that was probably off of a 454 Chevelle- dual non-snorkle inlets similar to 1970 340, but with a lid that was the same dia. as the air filter element. It had Corvette rallye wheels with no trim rings, and L70-15 tires all around. The only hint as to the real nature of the beast was the spacers between the intake and the (orange painted) aluminum heads. With 3.42 gears, this thing would give up a big hole shot, and then go honkin' past about anything in high gear. Apparently was 550 cubes in a tall deck block. I personally know of a 420+ inch small block that even has had the W-2 logo massaged off of the old castings and everything including the intake is painted to look stock save for the ceramic coated headers. Probably good for low tens, given the rest of the build.

Yeah, I've been engineering the combo to try to take away as much low end torque (Bigger carb, single plane insead of an RPM Air gap and 112 lobe centers) as I can. I want to try to keep the "shiney side up" if at all possible
This mini stroker (essentially a 318 bore 360-ish stroke) should be a good combination for bracket racing in a short light combo, to keep from flipping I'm starting out with 4.56 gears 9thanks B1Frank!) and a deep gear 998 auto with a 3200-ish stall but with a much smaller 26" x 9.5" Hoosier QTP instead of the 29 x 11.5" I was running. I'm doing 1/8th mile so I'll have to go to the taller tire (or less gear) to run the 1/4 once I get her all sorted out. 
Wise, with that bob weight and stroke that pup is just cryin for a set of main studs with pro-gram caps a 250ish @ .050 solid roller and a little set of wheelie bars and maybe a little shave on the heads

Yeah, thought about that. To be honest I just want something that'll go rounds and have fun with whatever ET it runs.....With bracket racing I like to leave first and that would really be the advantage of such a small car that'll be a very small target to chase to the stripe in the 1/8th mile....I'll probably see how fast it'll go and then back it off a couple tenths with a Vac secondary and try to make it as consistent as a swiss watch.
For sure I got an easy 600hp crank and rods in a 450-ish motor, that's ok though cuase it's an interesting combo...if I want to turn up the wick I'll find a real 340 block and just buy slugs and maybe caps then.
Mocked up the oil pump and pan....naturally the big fat rods required knocking down the pump pick up boss with the ol' handy mini side grinder. I went low buck using a rear sump truck pan, i thought about building a scraper for it but the main problem of starvation under a high G launch is solved with the truck pan.....nice to not have to worry about a big ol honkin K frame for a change!!!

I got to and I'd offer this suggestion to either Edelbrock or Indy..... Come up with an 'EZ' Style approach and make a smallblock head with a W2/5 (offset rocker) style intake with a standard header flange exhaust....something that will flow 280 @.500 right out of the box without needing an exotic header to work in any A/B/E body. Make a 2.02 that will fit in any 318 based block and maybe a high-flow 2.08 or larger valve Super Victor/Big Easy for the bigger bores w/custom pistons; both should have a modern compact heart shaped combustion chamber of maybe 60cc's that would work with a zero deck flat top. The idea of an off the shelf bona-fide High quality and affordable 500hp smallblock head could be developed/made pretty easily with the right combination of existing molds. Ford and Chevy have had this option for years and years, done right I can't see why this head would cost more than 100.00 or so more than a standard RPM style head. Also why can't anybody make a high quality but cheap mass-produced stamped offset rocker for guys who want to run the option of a W2 style intake with a mild hydraulic cam? This would take advantage of the much higher lift XE style street grinds without having to shell out mega bucks for an entire roller rocker valvetrain.

I agree about your head sugestion, the eddy could at least for sure use a better shaped chamber, they could at least rob the one from there magnum head. The one thing about the stamped W2 rocker is the guys who run W2 style heads typically run pretty big cams that need really stiff springs and those tend to punch through stamped steel rockers. The stamping process makes a weak area right in the PR cup, to make them strong enough they would need to be very thick and then they would be very heavy and require even stiffer springs and the W2 style valve train is not very stable as is. However, I think it should be easy enough to make a decent set of say $300 aluminum rockers with a bushing where the shaft rides there would be a big market for those .

you guys running 0 deck flat tops..
and the .560" or bigger cams..?
what did you do for valve to piston clearence?
did you have to fly cut the piston tops?
ive got a .030" over 360 0 deck kb flat tops
with ported j-heads,offset intake rockers and no pushrod pinch. 280" intake runner volume..
going 11.20's with a Tiney .485" solid flat tappet.
want to go .550" roller..but need to contemplate piston machining..
Did you guys find clearence necessary?
id like to just do a cam/valve spring swap..with the motor in the car..
a cam should really pick my duster up..
cheapst
My motor is 5 out of the hole and the biggest cam i could run is 591/610 lift and that is with 1.6 rockers, with KB flat tops no cutting
Duration is more of a factor in VtoP clearance than lift. I have a roller that is 230* at .050 and .605 lift, KB107's .006 out of the hole, with over .120 clearance on both sides.

Don't forget head gasket thickness, VJ depth, head millling, rod ratio, LSA, rate of cam lift... all those thing and more come into play

I just read an article in Engine Masters magazine that stated Indy sells an eddy head that has the pushrod hole relocated and uses the W2 offset intake rocker.

500 HP will put a 3200 lb. car less than 10.50 @ almost 127 MPH.
3000 lbs.......about 10.20 @ over 129 MPH.
2800 lbs.......9.90s @ over 132 MPH.
___________
3200 x 500fwhp = 10.81@124
3000 = 10.58@127
2800 = 10.34@130

Well I just called Trickflow and the planned release day for their small block mopar head is in September. I personally am not interested in this head but while talking to their tech department I asked if they planned on releasing another BETTER head in the future like they did with the big block head. They are pretty tite lipped but he said nothing at this time. He did go on to say they were both happy and surprised by the mopar markets sales numbers.

I’m sure a 10.5:1 360 with the TF heads and a smallish roller would break 500hp.
The question would be, how small could the cam be and still get you to the 500hp mark.

I'm not big on throwing horsepower numbers out there but my Sons stock crank 360 has gone a nice string of 6.54's in a 3200 pound car with a 727 and 4.10 gears. Edelbrock heads and a 610 lift roller cam. That should be a hair over 500 I would think.

============================
* 'Mandatory' 9 year old topic update! *
============================
Major topic-revival from the almost forgotten basement.
9 years since this topic started.
Plenty of new stuff has come out since then so it should be easier to get to '500hp' nowadays.
To kick it off again;
I'm considering to wake up my current stock stroke and dailydriven 360ci engine in a '73 Dart a bit more.
This engine has a 11.3:1cr, polished '302' heads with 60/61cc chambers.
KB-pistons, balanced assembly. AirGap intake.
(Hydr.) CompCams XE256H, used with solid lifters and Crane 1.5 rockers.
208-210 cranking compression. Running on Propane fuel.
Doug's full length headers into a dual 2.5" exhaust system with X-pipe and Borla mufflers.
Would like to keep the shortblock/crank ass. as is (zero-deck), and considering going to a solid roller and some SideWinder heads perhaps.
Won't mind a little lopey idle, and I know this is contradictory, but fuel economy is a consideration so low/mid range torque/efficiency is King.
Like to keep it N/A.
What are today's options of getting at (around) '500hp' while keeping the engine docile enough for daily use and not be a handful to drive?
For what it might be worth you can get away with quite a mean smallblock and keep some kind of drivability and fueleconomy good enough for daily driving if you just have it tuned right and have a happy combo of parts. 15 Years ago i had a 340 with a 260+@0.050 solidroller cam in my duster and i drove that thing everyhwere all the time,sure it had less converter than optimum for racing but the thing ran excelent on the street and didnt eat endless amounts of fuel as long as i keept my foot out of it,it sure didnt fool anyone into believing it was a stock 318 when it was ratling windows already at idle and was flat out screaming when turning 7500rpm but the thing was deadreliable, and on the open roads with a soft foot fuelconcuption stayed at about 1.2Liters/10km even ran it at pretty much 1L/10Km flat in some instances running about 90km/h with no stoping or accelerations. However this thing was probably not realy a 500Hp 340,probably more likely a 480hp 340.

Docile is in the eyes of the beholder but here was my combo that made a touch under 500 according to the wallace calculators. .040 360 KB107 pistons zero deck with .039 quench Shady Dell Stage II ported Edelbrocks 258@.050 solid roller Victor 340 intake 830 carb It went 11.16@120.5 wieghing 3525lbs in good air for here. It had a big cam, and big converter but it was very driveable. It was in the car for 5 years and did 4 drag weeks in that time. It got a best of 15MPG on the highway on drag week. I never measured it in town, but it wasn't good due the converter and my right foot lol. Pretty easy on parts, it ate the thrust once for reasons unknown, and we jammed a new crank in it over the weekend and went on drag week the next. I changed lifters once in 5 years and I changed the springs($100) every year before drag week as insurance.

Shady Dell Stage II ported Edelbrocks
258@.050 solid roller
Victor 340 intake
830 carb
I’d expect that to easily make 500+

My stock stroke, 11:1, W2 head, MP intake, antique Cam Dynamics .620/.640 roller, too small carb, 360 was about 525 in decent air according to my Moroso dream wheel.
If the results don't match the theory, change the theory.

I’m gonna say the xe256 cam and 302 heads aren’t the kind of items I’d be seeking out to use if the goal was truly 500hp.
Maybe with some boost.
The sidewinder heads flowing an honest 265+, a small roller like a Comp XR280R, with the other stuff you already have should get you close.
Not sure how the propane fits into the equation as far as power output goes.

In my view 'docile' could mean power brakes should still be possible. But of course an elec. vacuum pump could take care of that perhaps these days.
Of course 'Docile' is easy to interpret differently for anyone.
Let's say, could you wait for 5 minutes for a traffic light?
How about 10-15 minutes of idling in a traffic jam, all without overheating or fouling plugs?
Powerbrakes could be made to work with a vacumpump or possbily hydroboost. My old 340 with a 260+@.050 solid roller didnt have any problem what so ever with a 8hour lap around Västerås during a very warm cruisenight at PowerBigmeet, Thing was pretty much runing at a 800rpm idle for 8 hours straight except for one occasion when i got of the cruise to get some fuel and found myself alone on a empty street where i gave it one big step on the loud pedal and the thing sure responded just like usual. Thing didnt even have a huge colingtsystem,just a radiator out of a 4cylind Ford Scorpio and a MRGasket 16" electric fan and never ran hot at all despite what internet toughguys tried to tell me and that was with a tallfilled block. In my opinion its mostly about having an happy combo that is well tuned to stay out of trouble with heat and fouled pluggs. I’m gonna say the xe256 cam and 302 heads aren’t the kind of items I’d be seeking out to use if the goal was truly 500hp.
Maybe with some boost.

Not sure how the propane fits into the equation as far as power output goes. Thats not a bad idea you have there,if those sidewinderheads are real efficient and everything else is just right they might just reach close to 500hp with that cam, Thats actualy the last cam i ran before my worn out 340 finaly expired it sure has a long flat powerdelivery ,Its a very nice running cam in a stock stroke 340 and might be even better in a 360.

You’ll have to decide for yourself how rough an idle you can live with.......cam accordingly..... and the final combination of parts you assemble will make what it makes.
I was talking with a customer yesterday that just finished putting some finishing touches on the install of a 418 6bbl in a challenger with ex manifolds and a stick.
That motor used a fast rate solid lifter cam, 242@.050....... he said the thing was very mellow.
How mild or wild it is, is mostly about how each person perceives it.

Very true, I personally thought the .484 hyd. had more of a lope than the DC.590" solid I changed to in my 10.1 340 and it drove real smooth on the street...nobody would probably use any of those cams today though.
The .290@.050 comp solid I ran in my 440SP motor ticked over at just over 900rpm, I wouldn't call that a wild cam either, and it was only a 10 sec. brkt car, most wouldn't go anywhere near that much duration unless all out max effort, but that was with ported 906's.

You’ll have to decide for yourself how rough an idle you can live with.......cam accordingly..... and the final combination of parts you assemble will make what it makes.
I was talking with a customer yesterday that just finished putting some finishing touches on the install of a 418 6bbl in a challenger with ex manifolds and a stick.
That motor used a fast rate solid lifter cam, 242@.050....... he said the thing was very mellow.
How mild or wild it is, is mostly about how each person perceives it. That is true. Everyones idea of mild and good idle quality can be all over the map. But the rest if the cam and motor specs matter too. That cam might only have 50° overlap, and/or high compression, effecting significantly idle characteristics. And the stick also changes the perceived mildness as the motor is not loaded at idle like an auto. I too would be looking at a small solid.

The 302-heads and XE256 cam were chosen purely for streetdriving.
Now that I've driven with this engine for some 2 months, goals might have changed and I started thinking, I *think* I 'need' more power.
A cam and headchange might be in the works perhaps.
I'm running a XR274R roller in a 496ci stroker, which has a very obvious idle. Running a stock stall convertor behind it and it's pushing against it. This engine however is quite a handful because of the long-ram intakes with 2 carbs doing kinda 'whatever they like', according to the AFR-gauges in the car.
I can only wonder how an even bigger cam would behave in a way smaller 360ci.
Propane can be seen as a 100+ octane fuel but with a little less energy.
An XR280R in a 360 is not going to fool anyone into believing that that 360 is a stock engine and it sure wont appreciate a stock converter either,it probably wont even idle in gear with that. But it will idle at 750-800rpm until you are out of gas if everything else is right and yes it has an idle that you will notice, In my 340 it had a nice long powercurve even if it might have been alitle soft down low,but that was in a seriously worn out engine. A friends Edelbrock RPM headed tunnelramed 383smallblock with that cam was perfectly tuned and was very mild manered all around,had a fairly tight 3000rpm converter,could idle forewer,started by just a very quick twist of the key,but standing still just slam the throtle wideopen and the thing would smoke its 28x10.5 ET-STreet tires for probably 200meters(thats about 1/8mile for you Americans) and go about 100km/h(about 60mph) when letting of,thats how a well tuned 500HP smallblock behaves when everything is set up right and ran mid to low 11s in the quartermile shifting at about 6000rpm. Hey we all need more power and there is always tradeofs but rest asure that build it right and tune it just right and you can make something that is wild in most people books behave quite good on the street even if it wont idle like that stock 318,but its not for everyone,a real 500 horse engine will eat stock drivelineparts over time unless you run it on ice or never step on it,and it will show alitle attitude. BTW how is that 100+ octane measured? I know that we have a way different measuring system up here in Sweden compared to the American system.

Try a turbo. With a bone stock 318,(deck O-ringed with copper head gaskets), blowing through the 2bbl intake,(draw through system), with a 800 Thermoquad at 26lbs. of boost, 536hp&586 ftlbs.
I have since upgraded cam, heads, intake and gone to blowthrough so it needs less boost. I am hoping to have the motor bolted to the dyno this weekend.
I dynod the 318 with the stock 2bbl at the time, just advanced the cam a bunch to try to get some cylinder pressure. It made 160 hp. 1 hour later with the turbo 536 hp. It cost me less than a grand.

And I'm already at 210psi cranking compression with the 360ci.
A cam change would “cureâ€(?) that

I'm running with a 360 engine that made 464WHP using Super Victor Intake and Mighty Demon 750. So I've changed to Tunnel Ram and two Mighty Demons 750. I didn't run on dyno after that but the time on the track drop from 6.98 to 6.73. You can see the setup at this video: https://www.youtube.com/watch?v=ap8u2OfaBCw

Ya see...that idle. Looks like it was @ 1100? I could live with that for a driver. imagine seein' that thing pull up at a stop light.  the joy.

I agree John! On my SV I did a deep port match and a basic plenum rework. I did the same work on tunnel ram. Measuring Weiand Tunnel Ram I can see that it has a lot of little points where I could work, starting by port match and going through runner until the plenum...

You're right! Idle is 1100 RPM and believe me, that's amazing to ride on the street. Maybe in a 408" you can drop the idle around 1000 RPM easily...

I still have my super Victor Intake and did end up going 9.74 with it on my 408 but with two ported Indy intakes on the shelf not sure if I would ever try it again or not. Finally had a chance to watch your video last night and the car sounds great. Looks like a fun ride. Go out and have some fun

You're right! Idle is 1100 RPM and believe me, that's amazing to ride on the street. Maybe in a 408" you can drop the idle around 1000 RPM easily... I am a big believer in having a high idle with a flat tappet cam. Have a 1 wire alternator that charges from 1500 rpm on up. So at the track i keep it at 1500 so its always charging
