B1 416 stroker....

[B1owner]

o.K Guys,
I just put my 416 together and got it tuned a little. Im getting ready in a couple of weeks to take it to the track and I wondered what I should expect from it, that way i'll know if its "in the ballpark" or not. Here's what I got...the car is an all steel Demon with full interior....4:56 gear, alum autodrag wheels, 340, .030 over with 12:1 diamonds, (about .045 quench),4"mopar crank, Fully ported Brodix B1-BA's from a B1 specialist (Hemphill's), offset intake rollers rockers (ect), victor manifold, custom ground Cammotion mechanical stick with 265 @ .050 and .610 intake lift and .565 exhaust, 1 3/4 supercomp headers, 727 with a super street fighter torque converter (flashes about 4000) massaged 750 holley, mechanical fuel pump ect....anyone wanna give me a guideline? I see in these forums you folks are more than helpful to others with similar question so i hope you can tell me what to expect...Thanks guys.. Terry

Well Terry without any head flow numbers and some other information you left out I'd guess low 11's high 10's if you have some sort of decent chassis and tire combo. If not then probably high 11's if you can get it hooked up at all.

[B1owner]

Sorry, tires are 9 inch Mickeys slicks, and the only real chassis change from stock is 3000lb Superstock springs from Mancini. I did have the head flow #'s but I lost them and cant remember what they were... when I gave the #'s to my cam dealer to get the cam done he remarked that he wasnt able to get a set of Edelbrocks to flow as good (he's not a chevy or ford specialist-but a real mopar shop owner). But Ill look around for the flow #'s.

[B1owner]

I cant find my head flow numbers anywhere. I tore the house apart looking for them. Anyone else want to take an educated guess at what they flow and tell me what you think the car might run and what I should be satisfied with and what not to be happy with? All Im looking for is a guide line. I think the heads flow around what a ported W-2 does, more or less.

[B1owner]

Would you do it for a scooby snack? I sure would appreciate it. Thanks..Terry

[lenweiler]

I've a milder setup. And I'm told to expect high 10's. I've seen combo's like yours go mid 10's. They were hooking, of course. Good luck!

Edelbrock isnt a race head but a good replacement head.But i know Shady dell speed shop built a Eddy heads small block thats run likes 9.90s at 131 mph but they only flow like 260.I BELIEVE.the car weigh 3100 pounds

[B1owner]

Yeah I do remember my heads do flow 280 something on the intake, but thats all i remember. Exahaust was the real hi-light of the heads but cant recall the numbers.

[skankweirdall]

3100 pound car going 9.90 with 270 cfm head flow? Only with nitrous, a blower or a turbo. 280 is ok so I still say low 11's. I've heard those heads aren't that great although I have no personal experience at that.

BTW I know I ain't the be all and end all but my W5 heads flow 300 at .600, the car weighs 3070 with me in it, has 12.7:1 compression and a lot of tire and gear. It runs 10.70's on a good day with a best of 10.65, but mine is only a 363 cube motor.

[eric414]

The eddy head motor that is going 9.90s RyanJ at shady dell did the motor.Oh i did lie to you about the ET on this eddy head small block after finding the post.the car went 9.80s@131.If you go back to the drag race section under "how much power from a w2 headed small block" first page,the first RYANJ post and you will see the motor was a 410 eddy head that flowed 263.He didnt say anything Nitrous.We will have to ask Ryan.Ryan is that demon using nitrous to run 9.80s?

[mgreen2994]

ive never try the eddy heads but i see no reason that you shouldnt be able to get in the 9s on july 4 1976 a friend of mine run 10. 31 at green valley texas with a 318 .30 over with cast 2.02 heads

Yeah but you neglected the rest of what he did say.

I have a Customers Edelbrock head 410" motor that runs 9.80 @ 131 in a 3100 lb Demon. His heads peak flowed 263 on my bench. Using the HP per CFM equation, the #'s don't even come close to adding up.

This is certainly an exception and not the rule.

Thanks for the input guys..keep the opinions coming. ..the more I get the better picture of expectancy to give the car's performance...

[eric414]

On Ryan site the Eddy flow 298 so his ported eddy flow more than the B1s that B1 onwer has if the heads flow around about 280.i really dont know im just going by what the man said.I think a Eddy head motor going 9.80s is awesome to me.I had a 360 with 576 heads and a solid cam running 10.60s.But i got something coming real soon that is AWESOME

[B1owner]

I THINK they flowed around 280 or so. The B1-BA will flow WELL over 300 if you get serious with the porting. Its a fact.The exhaust is the real treat on these...but lots of folks dont seem to pay much attention to that. For what its worth, check out www.shadydellspeedshop.com/brodixb1ba.htm . Anyway, my heads were ported pretty well, put its obvious looking at them that there's room for more port work. Im not really looking for a head debate here, and I know dollar for dollar Edleboogies cant be beat with a stick. But I bought these B1's about 11 years ago when they first came out and they are what Ive got.( One of the first set cast) I dont regret it. They just arent done to the max. Just looking for some more imput before I get more money to take it to test-n-tune night at the track to get it sorted out and tuned. Thanks Terry

Tom Hemphill is sharp, I would'nt worry about the heads. Take it to the track and find out.

That Edelbrock head motor I built..... 750 DP, Victor 340, E heads, flowed 263 Intake 220 Exhaust, 2.05"/1.60" 12.2:1, The pistons are custom Ross flat tops, But nothing too special, still a 1/16" ring pack, .984" Chrysler pins. Weigh around 448 gram. 4.04" bore X 4" crank = 410" The Rods are Eagle 6.123" H beams. It's a '71 360 block I decked to some weird deck height to eliminate the O ring grooves. I think it's down to like 9.555". Now has Cometics on it. It has tall fill hard block, ARP studs. Has out of box MP 360 4" Forged Crank. Moroso 8 Qt pan & pickup. I tubed the block, has Crane roller lifters, Custom Ground Comp Cams Solid Roller. It's around .630" 278/284 @ .050" 108 CL in at 105. Headers are 1 7/8" Heddman Hustlers. Car weighs 3100 lbs, it's a '72 Demon, has a powerglide... 9.80 @ 131 so far on gasoline. No nitrous, no blower, no nothing..... It's just a decent combo, what do you want me to tell you? I have another set running 10.20 @ 129 in similar car except it has 727, and has more basic off shelf piston combo with a Hughes Flat tappet..... When the combo is right, anything can fly.

[heigleracing]

hookin up is alot of what kind of ET you can expect.

I run strokers in my car 2820lb with 260 lb driver and go 10.20'. your combo should go 10.90 with a car that has some hooking problems,

[heigleracing]

dude, did you work on a motor for a fella named rick ronde??

his motor really runs on the pump gas. If it was you, nice job.
Also, truer words have never been spoken when you said that when the combo is right it will fly. I have had high dollar stuff that wouldn't run and mild stuff that could boogie.
Experience with trying different combo's is priceless. I could tell ya all about a couple of my back up motors and how well they ran in my car and you'all might just crap. never say never about these mopars!!

[B1owner]

Well I ran the car an it went 11.13 right out of the box with no tuning at all except setting the timing at 35 degrees. !0.90's shouldnt be a problem. Thanks for all the input..
