Big Block Edelbrock limitations.

It's interesting, but not necessary, unless you want more than your original power level goals.

Sadly, that's the nature of humans. We always want more. Not sure if my wallet could afford the stroker. I'm going to look for Dulmage's book.

I think if you find a copy, you'll be selling those heads to fund some of the build when you see how unnecessary they are for your power level. LOL They'll still be nice to have though, regardless.
 
Problem is guys believe ragazine articles and dyno numbers. Years ago when 400 horsepower articles became boring they jumped to 500 and then 600,700,800, etc etc. the guys writing this trash are given parts for free or at reduced prices to promote their products. Most of these builds never make it to the dragstrip because the cat would be out of the bag. Don’t drink the koolaid and believe everything you hear or read.

Very well put!!!
 
Yes I should've mentioned that on my post...we all know what it takes to make that sort of hp, I think there dyno was around 100hp out on the minus side....guess it sells parts.

Thank you. Not trying to build to anything specific. It's a mostly street car that I would like to get to mid 11s. The thought is that if I'm going to go through the engine, it should be better/faster than it is.

We just finished a 440, that has the 516 heads with oversized valves NO port work, flat top pistons and just .525 lift cam, that ran 11.11 and 120 in a Duster street strip car, your will not need a stroker motor to run mid 11s

Well, that opens up a bunch more questions. Weight, roller, compression,fuel, carb, gear, etc?
Mine is a full weight street car, through the exhaust with the sway bar attached. Takes a lot more to move mine.

Surely you did some bowl work. otherwise increasing the valve size had an adverse affect on the 516.

Weight 3480 with driver, flat tappet cam, 10.7 on the comp, pump gas, at the track splash of 110 octane, 850 carb, 3.91 out back.
 
As a bit of a closer guide for what it takes to run your mid 11's.....a guy here with a s/strip '70 Challenger 440 that runs ootb Eddy's, around 10.5:1CR, 3800lbs+?, a Comp Cams..550"/570" lift solid, 850DP I think, 3500 stall, 3.73's/10.5 Hoosiers on mono's/caltracs and has run a best of 11.5@118 which is around 508fwhp.
 
Once again guys it comes down to building the right combo and not a bunch of parts working against each other. Heck I was running 9.80’s with ported 906 heads, TRW pistons, and stock cranks back in the late 1980’s early 1990’s. These cars should be flying now

And today, over here, Mopar guys are running anything from 500>572 motors to run those 9.80 times, perhaps a bit quicker from some that are race cars only, and that includes Hemis. There is 1 guy thats got it sorted and runs 9.5's/141 with a 580 wedge in a 4000lb all steel brkt car, but the rest well, I don't know if its down to chassis or the fact that they are all brkt racing and fast isn't the main consideration, its not money cos they are spending it, gotta be the combo.

Back in the day 1989>1991 all I had was a stock bottom end 440-6 block@less than 10:1 with some 2.14 906's ported some (probably not much more than 260cfm?) and the old 290@.50" .650" McCandless sft cam and made 531fwhp (nothing special I know) according to weight/mph with only an 850DP and a rubbish Team G intake.

Even tho I have a stroker , I`m not getting impressed by their dragstrip times, when a friends 350 sbc runs low nines -------
 
Well keep in mind yall say these newer cars with better tech and bigger strokers should be runnin faster........BUT they share one thing in common with the big boys like top fuel, funny car and pro stock. Tire technology. Tire technology has always lagged behind and been the limiting factor. It still is.
