ford racing fans.......

It would be pretty hard to hit 300 rwhp with a Cobra intake and GT-40 heads. There are 4 different GT-40 heads that I know of, they are: GT-40 stock on the SVT Cobra, GT-40P, GT-40Y, and GT-40X. The "Y" and "X" heads are aluminum with the "X" being the better of the two. They just don't flow nearly as well as say Trickflow, Edelbrock, and especially AFR. You don't need a big cam either, really, you just need one that matches the parts you're going to use. For example if a head makes max flow around .500 lift (all GT-40's) why go with a cam with more than that? As far as duration, you don't need a lot of that either. The e-cam has plenty of duration (282 intake/exhaust). That being said, GT-40 heads would still be a huge increase in power over the stock E7's, especially when matched with a Cobra intake and a decent camshaft.

Check this out, they used lots of FRPP parts on that car.

If you're gonna spend the extra money getting them ported you might as well just buy Trick Flow heads. They flow great out of the box and respond awesome to porting if thats what you want in the future.

try looking into the holley systemax package... i think edelbrock and trick flow have packages to get you near the 300hp range. I think i have seen them at http://www.summitracing.com... just my 2 cents. btw you could get the gt40 stuff off a 5.0 explore
