How fast have you gone with a standard port bb head?

And or how much horsepower? And your combo please?

Customers car:
14:1 493, mild roller, tg4500 intake, 1050 carb, 335cfm std port SR's in a 2300lb S/G "street roadster".
As I recall it went like 8.80's in decent air......it was just under 700hp.
It was a very low maintenance bracket build.

Yep, that would do it. I wonder how the Trick Flows would compare to the std port SR heads.

I think the answer to the question is how fast will 700 hp go in your car. Obviously a 700 hp engine in a rail will go a ton faster than in an Imperial with street tires.

It is fairly easy to build a 700 hp std port engine these days. Buy some Trick Flow heads, add a solid roller cam and some decent compression and you are there.

My old pump gas 518 C.I. low deck pump gas stroker (10.29 to 1 comp. ratio)ran a best of 10.30 at 127.8 MPH through the 3.0 inch exhaust system with the Magnaflow 14x3 inch ovals muffs mounted at rear bumper with me in my 1971 Duster weighing 3450 lbs. with the six pack and air cleaner on the CNC ported Eddy RPM heads.
That motor on a DTS engine dyno in Ontario, CA with a .050 shorter stroke crank and 1.0 point less compression and a set of big valve mildly ported 906 heads made 612 HP @ 5500 RPM and 644 Ft. Lbs. at 4500 RPM
I was really happy with that motor and the results it would produce with the changes I made on it, the last combination was a set of Indy SR M.W. heads and a Indy 400-3 intake and a holley 9375 non HP carb made 727 HP at 4300 ft in Klamath Falls OR. at 4300 ft. altitude. That was the last changes I made on that car and it made the car run 9.993 at 134.7 MPH through the full exhaust and on 91 octane OR non ethanol pump swill at Woodburn in late summer
You can made decent power with the standard port heads on a BB Mopar
Better heads will make more power also with no other changes
Now, how fast do you want to go

440 six pack rods, Ross domed pistons, 915 heads, 2.14/1.88 Herbert roller, Team G, 1050. 575hp @ 6100 rpm. 9.97 @ 135 mph in 3,000 lb Cuda.

I dont think 750hp would be all that hard to reach with some 350cfm heads on a high compression roller stroker build.

Then, as you say....... Just depends on what you bolt it into.

And there's also boost or spray.

'Nother one:
14:1 528, b1bs heads flowing around 325. M1 TR with 2 x 750's, .690 roller, made right about 720hp @ 6000rpm.
Went 9.71 @ 140 in a 3700lb 68 charger R/T.

One more:
12:1 low deck 451, stage 6's with mild porting(300cfm), RB TG4500, .685 roller, made 650hp, went 9.31 @ 143 in a 2650lb S/G 70 Cuda.

My brothers 512 15.1 std port trick flows ported soild roller, under .700 with 1.6 rockers nothing super fancy in a 67 cuda stock suspension went 9.56 best at 3298 with him in it .. I'm sure there is more in it as we got it together at the end of the season. Plus it was set up to be sprayed .. Nos converter etc ..

Race car?
Street car?

135 MPH

440 block and crank, alum rods, 11.2 to 1 Ross pistons, unported Edelbrock rpm heads, 304/640 ultradyne flat tappet cam, Isky ductile rockers, 4150 flange M-1 intake, 4150 to dominator 2" adapter with two cheater spray bars installed in it, and an 1150 Dominator on top.

simple straight-forward combo that went a best of 9.96-133 on motor alone, and 8.92-149 on spray.

2950lb 70 Challenger, glide and 9" hughes converter, 4.30 geared 8 3/4.
Dependable and lots of fun!

Dead stock 906 heads, not even a 3 angle valve job, on a 3200 pound Dart, 10.80s-122 .30 over flat tops.

Funny you ask cos my goal is to have one of or the fastest standard port window street cars at my cubes(470)and wt. now around 3050 n/a and hopefully some will share that............Last time out I went a 1.33 60 ft. and 6.15 @ 109 just lifting before the finish but went 111.78 2 years prior w/a poor 1.4? and 6.20 et so how much power is that? Been 9.79 @ 135.59 4+ years ago first pass at 3200+ lbs........

Combo; 470 stroker w/a offset ground 413 forged crank, eagle 6.385 chevy rods, JE 12.1.1 true comp. pistons, home ported 84cc(now 72)rpm's w/a 2.19 intake,Victor jr. w/adapter fully ported by Ed Mosler w/some minor adjusting since by me, an Isky solid roller w/.680-.660 and 276-281 @ .050,a home built 1050 dominator,2" Hooker Fender Wells w/3 1/2" side pipes into bullets,a Darrell Parks built 727 stock basically and rollerized,8" 5200+ Continental vert, freshly built Dr.Diff 8 3/4 nodular housing w/4/10's, 35 spline axles, and 28.10.5 w's on 10" Billet Specialties wheels............I`m curious too about wt and et's..............

Cam? Converter? Gears?? Intake/carb?

Mild solid cam, Crane? I'll have to ask my partner, 9 inch TCI , 5.13, TM7 800 holly with a 850 baseplate and 2 inch wooden spacer I made. Tried the Weiand, didn't help. Six-pac scoop on a glass hood. Car weighted 3021 but KK weighted 260. Headers by Ed, fender well but made better than Hooker, didn't interfere with tire. Looked like a big spider on the engine stand. Tore up every 8 inch converter we put in it, probably made better now. Won a lot of money with that car.

There are iron headed wedge Super Stock cars that run low 9s at pretty hefty weights.....so take that for what it's worth. But that makes some alum headed strokers seem not so impressive. Too many just throw "cool guy" parts at motors instead of carefully planning the combo.

NOT saying you should use iron heads, or not build a stroker............just saying that a good combo is what makes power, not just throwing parts in a pile

133 mph. Standard window SR's. 12.5 cr.

Best mph 139 once, usually 136-137...standard port B1BS,14.2-1

Enough to run a 9.70, I could of said 9.69, but I didn't.

You suck................lol I say 9.65 or better...........

Thanks for the responses. I ask because I have a lowly 383 and I am putting portted sidewinder heads and a tr on it. But my future plan is to build a bigger short block eventually.
My current combo is 12.5 to 1 trw domes, mp590 cam. 2800lb valiant. I'm hoping at least 10.7s. But eventually wanna build a short block for 10.00 or better. Looks like these heads can do the trick.

Assuming it doesnt have a crappy converter and totally the wrong gear/tire combo, if that doesn't run at least 10.70's (at a track that's below 1500'-ish elevation), there's something seriously wrong with it.

Fast68,
For now it has the wrong gear 4.56 and 31x13.5 slicks. I just bought the car in June and only ran it once and was disappointed with a 11.80@113.33. So I decided it was time to freshen up the bottom end and new rings, and new heads. I agree it should go quicker than 10.7 but I don't want to be too optimistic. I do plan on changing gears to a 4.88 or 5.13.

'69 Cuda stock 440-6pk bottom end, 9.8:1, 2.14/1.81 906's mild port, 3000lbs all in, CC.650/.650 290@.050 SFT cam, Team G dom w/adapter to 850DP, 727, stock front end w/90/10's, 4800 verter, Hoosier 14x32, 4.88's, l/bars c/overs

10.71@125 NA 1.46 60ft> 9.96@133.9 1.38 60ft with small Hit in 1990
11.23@118 with bone stock 906's.

I think it would've gone quicker with a cam where the intake closed somewhat earlier for a bit more effective stroke/CP....was at 0 sea, knowledge wasn't the best back then, like running 4psi in the slicks!

290@050? 😳

Way to big for you, as you already know.

lol I think my mp590 is too big with 271@050. For only 383 ci.

65 Belevadere all steel we have gone 10.94 on pump gas with 915 heads 2.14 / 1.81 valves....Its a pump gas 440 Source 526 stroker. Its got more in it, we are fighting traction since the car is not tubbed. Its fast, streetable and fun to drive.

With a 526 that has to have some fast port speed

i have a duster 3120 with me in it with a 30 over 440 old indy econo i think heads (non offset rockers) with a old 262@50 solid predator cam 13.7 to 1 dominator and m1 intake ran a best of 9.89 in killer air at cecil md. ports are 270cc 330 cfm flow

My old DartSport had a low deck 451(400 block with 440 crank), MP 590 purpleshaft, ported Eddy heads, 727 with 8" ATI converter, 4.56 gears and 14x32 tires and weighed 3050# with me in it.

Ran 10.0's with a best of 9.96 in good air with a single Dominator.

Ran 9.90's with a best of 9.89 with a M1 TR and two 750 Quickfuel carbs. Extremely fun car, with 11.2 to 1 compression I ran pump gas on the street and mixed in a gallon of 110 octane as an additive. I'm guessing around 650HP.
I don't have any photos on this new computer.

Ummmm... not fast enough.

And it likes a lot of carburetor.....1.50 60ft on that 3400 steel tank plus driver.

Here's another combo, my mates 3150lbs Dart>

440, 12.7:1, MP.590sft, 273 rockers, MCH Eddy's (320cfm), Victor int, 1050 Dom, 5000 verter, SS springs, 4.56, 13x31's = 10.14@131

170mph, high 7s in a 1700lb rail dragster. 471B with flat-top Ross pistons, 3.9125" stroke, Racer Brown tight lash .660" roller, M1 tunnel ram with 2 x 850 Quickfuels. The heads are Edelbrock RPM's with 2.14x1.81" valves and stiff Lunati springs, Hughes rockers, etc. "Ancient Orange"
