True Paul, a lot more then just heads involved.

Dyno or track results? Anything besides talk? The cool factor is there for sure but.....

I have a shaker455 built 462 with edel d-ports. 242/248.598/603. it made 560hp and 600 torque.. I can dig out the dyno sheet and post them.

Any head sucks with an aftermarket intake or even a spacer with the second gen hood clearance. Especially the formula and flat hood.

Please do, any flow sheets?

Here ya go

Dyno of the V's that Tony Bischoff built and tested

Here's the dyno of dads engine, also built by Tony Bischoff with a set of older Edelbrock heads with bathtub chambers that were prepped and flowed by Tony

https://youtu.be/5WswK-m-zIA

As I mentioned, Tony stated that making 1,000 HP on pump gas with this engine is a piece of cake with a better cylinder head, whether that be V's, or high ports, or Tigers, or... there was no real preference.....but you're getting into a large lump of cash to do so. It was cheaper and made more sense to use what he had, so the E-heads were put back into service.

[Formulajones]

Here is the flow sheet on those older Edelbrocks after Tony reworked them. About as good as they get without changing valve angles and doing some welding. If you want to get that deep you may as well start with a bigger head, high port, Tiger, etc... Hence the reason the build took the direction it did.

LOL, a Formula with the stock hood. You won't get much of anything under that but stock stuff, ask me how I know.

If you want to get into making big power using these aftermarket heads and intakes, there are sacrifices that have to be made. This engine wouldn't even fit under dads hood in his 69 GTO which has ample clearance to begin with, and we are just talking about basic Edlebrock heads with a Victor intake and 2" spacer, nothing exotic, so a 2" raised fiberglass hood that "appears" stock was put in place to make things fit. These are also made for firebirds etc... What's interesting is that he uses a 2" super sucker under the carb, and everything fits with this hood. You have to get crafty, we use the L88 drop base that is deeper than other aftermarket stuff. So I would venture to say, removing that 2" super sucker would likely make things fit under the stock hood. But the super sucker is worth more than 20 hp on his engine.

It's just the road you go down, it starts a domino affect.

Sacrifices must be made to retain the coolest production hood ever made!

I couldn't agree more. I'll sacrifice some HP to keep that hood in place.

I probably should have clarified, when I mentioned the raised stock hood for the birds, I think those are only made for the first gens.

Its so easy that no one has done it yet.

That is no where near as good as it gets

[Formulajones]

It is with what he started with, unless you want to spend some money moving things around.

[Formulajones]

No offense, as I'm sure we all appreciate your input, but I'll take Tony's word over yours. Tony has plenty of experience and a proven track record to show he does what he says he can do.

[slowbird]

Didnt say it can't been done but saying it's easy is not true. If it was truly easy there would be lots of 1000hp pump gas engines around because everyone would want one and be building them. Heck making 1000+hp on race gas isnt easy. Plenty of people have tried and came up short.

[Formulajones]

Difficult is not the reason why you don't see many, because with the parts we have today it truly isn't hard to do.

It's just not seen because 90% of the population out there doesn't have the $25-$30,000 needed (or just isn't willing) to plunk down on an engine for a weekend toy.

We don't see ANY. Chris U (who builds John Snyders engines and many other badazz engines) with Marcella (who did Mike Leech's e-heads that made 1200+hp) pro port heads and intake came up short. But your right it's easy.
