I'm thinking about using the package deal from holley for the commander 950 and stealth ram intake on a 408 i'm in the process of building. The motor will have AFR 195cc eliminators, a custom hydrolic roller cam and shaft mounted rocker arms with about 600 lift at the valve, conservative duration in the mid 240s. Don't think it matters but i'm using a fully balanced forged rotating assembly from dart with SRP pistons. I want to run a stock hood and keep the drivability of EFI. Also projected horsepower is in the 520 range with a broad torque curve. I was planning on using the wideband version http://store.summitracing.com/partde...rsview=sku&Ns=


Anybody have any experience with this setup?

 

i run this combo on my 383 with 190cc patriot aluminum heads works excellent!! it should support that hp w/ the 58mm throttle body and youll want like 40lbh injectors.

it also clears the stock hood! and the pcm is easy to tune

What gasket do those heads take on the intake side. I know you can port the HSR out to a 1205 felpro which the AFRs I have use. I'm just wondering if you had to reradius the intake further up to compensate for that.

 

the patriots have a 1206 port and i did gasket match the intake and yes in my case it had enough material left to seal properly.
