Strokers are fairly common these days. I was wondering how many of you run these gas swilling monsters on the street.

For those that do, what is the car and combination? What kind of power does it make on pump gas? How are the street manners and mpg?

I'm getting back on my 541 build and wanted to hear from my Size Matters brethren. biggrin

Just a little 470" here. Had a single plane and big solid cam (gave it back to AndyF, it was his dyno mule short block). Didn't "turn on" till the revs came way up. Not fun. It's not a race car.

Changed to an Edelbrock dual plane, 850 Race Demon with annular boosters, an old skool MP528 solid cam, 1-7/8" TTI headers, 2-1/2" exhaust, Edelbrock heads max ported by late Jeff at Modern Cylinder Head, Passon alum case Hemi 4 speed, 354 gear. Talk about tire boiling fun but still with manners tame enough to drive to the local grocery store. Still has a very noticeable idle. I'm getting older (57) so swapping to exhaust manifolds and Borgeson power steering smile

What are your 541 specs?

Wife's daily driver from 1988 to 1997, '67 Fury III, 3.23 sure grip, 505 stroker, ~ 425 HP. Gas mileage not much worse than the original L code 440. Cam was, I think a Crane HMV 278? 452 (new) ported heads, standard valve sizes, CH4B intake, started off with a new Holley 750 POJ, don't recall what we ended up with. Idled nice, pulled the factory disc brake booster fine. Had constant battles with it running hot, never figured it out.

Got rid of the car, still got the engine.

1969 Super Bee. 512" low deck. 10.6:1 compression, Trick Flow 240 heads, Trick Flow single plane, Thumper 950.1&7/8 tti headers into 3" tti exhaust with X-pipe and Dynomax Ultra-Flow mufflers. .555/.563 solid lift cam. 18 spline Hemi 4-speed. 3.54 Dana. I don't know about MPG, but it made 491 hp at the wheels on corn-free 90 octane. I don't have the tune dialed in, but so far it drives nice. It's snappy at pretty much any RPM. I think there's probably another 10-12 HP in the tune. I know there is a lot more in the top end if I went with more cam, more head, more intake, more carb, more header tube.

493 not quite 500.

9:1 RPM heads cleaned up, M1 single plane TBI with an MP509 and in spite of that 500 HP 600 ft/lbs. All over and done with by 5300.

505" with 10.3:1 CR and small .545 Howards hydraulic roller. I usually run 91 no ethanol pump gas but can run the cheapest pump gas out there with no issues. The 11" converter and 3.54 gear makes it a pleasure to drive on the street.

The last time I checked mileage on an out of town trip, it pulled down 11 mpg. It essentially behaves like a super sized 440. More of EVERYTHING!

It weighed over 3,700 lbs. (with driver) the other day after I got it home from the track. It runs 11.1 @ 121 n/a and ran 10.01 @ 133 that day with a small shot of nitrous.

The best part is, it is very low maintenance other than having to change drag radials like you change diapers on a baby! grin

I also just have a little 470" Eagle crank,Manley rods,Diamond pistons @ 10.2:1, Eddy heads. Comp street solid roller, RPM intake, Holley 800dp. Idles at 900 made 430hp @ the tire @ 5500rpm(lots more there) and 500+ ft lbs all the way up. It's in a 69 B'cuda FB with a 4 spd and 3:73 gears. Very driveable and not hard on fuel if ya keep your foot out of it(hard to do). RPMs like a chain saw and pulls like a freight train...lol.....tons o' fun!!

a few YEARS ago, maybe 10 + years ago when i sold it. i had a 624 CI hemi road runner. after the cylinder wall cracked i had a 572 ci hemi built to replace it.
my friend built the motor. he built at least 10 600+ ci hemi motors.
my motor was a low compression budget motor with stage 5 heads with big valves and a bunch of used parts.
i think it had 500+ft lbs of torque at 1000 rpm. with low 3.23 gearing i could do 70 mph at 1800 RPM and i could still easily smoke the tires at will.

the biggest problem i had with it was the push rods kept burning up at the rocker arms pivots. big ci motors with large valves and fairly large cams require some spring pressure to work. the spring pressure along with running at low RPM causes this problem. it's a problem because the push rod / rocker arm pivot relies on splash oiling. at low RPM there isn't much oil splash. my friend solved the problem by using chevy type oil thru push rods where the oil goes thru the push rod to the pivot for oiling. once he did that we were good to go.

This 499" ran 6.85 in my 3,500lb Cuda. 250/260 FTS. Eddy heads ported by Modern. Kinda choppy idle, but not too bad. 10.9:1 on pump gas. It's sitting on the floor now.

That wedge came out for this 540:

But my gas mileage did not improve.

526 wedge. RPM heads, M1 intake, “1000 cfm” quick fuel 4150, 10.6 comp, cam specs I’d have to go look up. Shorty headers( nothing full length fits my car) 2600 stall, 3.23’s great street manners. Got 13.8mpg on the way to Carlisle ( 3 hour drive) at about 80-85mph.


526 cubes of angry wedge, pushbutton shifted, 9 passenger killer!

The 512" RB Duster I had isn't all that comparable to what Feets is doing, but FWIW:
440Source rotating assy, Indy EZ1 heads & single-plane, 750 or 850 Holley depending, Comp hyd roller that idled & ran "bigger" than specs indicated.
TTi headers into 3", 2.5" tailpipes, Milodon 8-quart, FBO/MSD6/F150 coil ignition.
727, 3500 stall, 3.91 & later 3.23 gear, 275/60R15s.
Could bust the street tires pretty much at will, sounded stout, basically pretty hysterical.
Never bothered to check MPG but it was a thirsty thing, guess 8-10 but never got enough highway use for accurate info.

Fueled my lust for a stock-appearing 438-505 low-deck for my Road Runner, I can tell ya that...

I'm playing with the 440 Source 543 kit (measures 541). My plan was to build it into a torque monster that still had a full conventional rpm range. It's going in a 5300 lb Imperial running 3.23 gears and power everything so street manners and are important. It should also be relatively low maintenance and reliable, too.

I called cam grinders and received answers that were all over the place. I've received suggestions that run from 230 duration well into the 250s. Lift suggestions are ranging from .540 to .630 but the heads might not accommodate that. I had settled on the Comp 236/242 hyd roller with .544/.541 lift but received a good suggestion and will look into that before dropping the money.

When I get the opportunity, I'll mock up the engine in the car and check for hood clearance. If possible, I'll run the intake off my TT440. It's the bottom half of a Weiand tunnel ram topped with a 390 cubic inch plenum and a forward facing 1700 cfm throttle body. A Holley Terminator will run fuel and spark. If I can't get that to fit I'll have to go back to a Performer RPM, throttle body injection, and a drop base air cleaner. That would move the torque curve 300 rpm earlier and cost about 30 hp up top.

I'll complete it with heavily ported Eddy RPM heads, TTi headers and 3" exhaust. I plan on having a relatively quiet exhaust note and opening some cutouts when I feel silly.

I've used Dynosim6 to model the engine. It doesn't do part throttle and idle quality well but I can get an idea what the build might do. Right now, it's rolling in well over 500 lb/ft at 2000 rpm and carrying 600 lb/ft from 3100 to 4900, 400 hp by 3400, 500 hp by 4100, and topping at 570 hp at 5200. If I can achieve those numbers I'll be happy.

I've attached the graph and table from the simulator.

I have a 528 Hemi in a pretty stock appearing 68 Coronet with a 4 speed and 3.54 Dana out back. This combo has been together for about 20 years now. The hemi runs a 245/256 @ .050” hydraulic roller cam, 10:1 compression, MP single 4bbl intake, MP heads with mild port, and 850 demon carb. It has great street manners with good idle and low range. The torque is incredible as the gas pedal enables the tire crayon mode in pretty much any gear at any speed. Only downfall so far is fuel economy isn’t great, but you don’t build something like this and expect a Prius. I’m probably 6-8 mpg around town but never really drive it easy, and really haven’t driven much on the highway to know how it does there.

Comp hydraulic roller lifters are garbage. My friend (and others) had no end of issues with them in his Dart. Once he swapped the lifters for the same Howards that I have, no more issues.

Mine is just a 493 so its a tad under 500 cubes. I think most know about my street/strip build in my 63 as its run a best of 10.76 through the pipes on 92 pump driven to track. It did dip back in the 10.70's last year at 10.78 and 125 mph but it only runs in the 70's on good days. Usually runs 10.80's. But we are building a supercharged eng for my boys Dart Feets so you might like that one since it will be boosted. Hope to have it out by this summer if all goes well. Ron

I have a 572 16 plug, 16 injector 10-71 Bowers blower. Should be on the street by this fall. Not a daily driver and definitely not a trailer queen. If I get 5 mpg I'll be happy.

Now add boost to the equation! My 545 blown hemi makes 850hp with 6# on premium pump swill.
