I think AI could set up a system to do this, even with an LTx intake. I would contact them to see what they know.

Afr 227's
solid roller
maybe a carbon fiber drive shaft
driveshaft isn't going to help him reach 500rwhp.

What are you wanting exactly? If it's a detailed blueprinted 500rwhp engine plan your looking for there are a few good engine builders out there ready for your phone call to get you going. If your wanting a detail parts list from LS1TECH good luck, you'll do good to get a generalization like everyone is throwing at you now, intake, heads, cam, tuning, etc.

wasnt saying a Cf drive shaft will get it done you jack ***
It's gonna take alot of work to put down 500rwhp. What I was trying to point out was just an example of something small that squeze out acouple more HP, and a CF driveshaft would yield a couple of Hp.

even a tornado!!! JK ****

On the heads, what manifold is needed and what heads are bolt ons that can utilize factory valve covers etc. I know thats a tall order, fitment, but some mods arent feasible in some cars.
I curently make 425 rwho, with a modest cam and a 396. I now AFR heads and a better cam will work, but getting an LT4 manifold isnt cheap anymore? How about a Edlebrock EFI Victor manifold? WIth an ELbo style adapter to fit a throtle body? Sorry for so many questions.

I've seen the Vic EFI intake and it's a pile IMHO. It does have the injector bosses in it already but it needs WAY too much port work to get it done for you. Plus it's super heavy, a Super Vic when it's done will come in at 1/2 the weight.

The intake manifold that I start from on the single planes varies depending on the head castings, TFS/AFR/LT4 all use one while the LT1 castings use another.

BTW that intake that aggie has on that motor is a Super Vic that I did for Jordon Musser last year at some point.

Thanks. Big dollars.
i had a friend get 480rwhp with an LT1 manifols and AFR heads with a 396. But he had 12.5 to 1 compression and a big solid roller. It idled at 850 rpm though, as it was tuned very well. But the heads were, as well as the manifold, ported beyond recognition.
Dont all the bog flowing AFR heads need the LT4 manifold though.?

The better the intake and heads are the less cam you can get away with and still make big power.

Shon Herron said he thought that AI could do it with an LT1 intake and well they proved him right. Just a "street ported" intake too.

I've got a 396 LT4 setup, running the AFR 227's fully CNC race ready. I haven't gotten it all hooked up and going, but hopefully that will change here in about a week, and be dyno'ed. I'm also running a monoblade TB, and solid roller cam with tons of lift. I'm just hoping to be at least 500 to the wheels when all tuned and done.
