I have my GT40p heads in the shop right now getting reworked a little. I am getting a 3 angle valve job, and stiffer valve springs. I am thinking of running the E303 cam but I am open to other choices. For an intake I think I am gonna go with an Explorer intake. With an E303, GT40P heads, and the explorer intake, what kind of gains should I expect?

That's it? That means I'm probably only making about 250 rwhp?! Damn Dyno is a heartbreaker.

I'll get (or have gotten) another 10-15RWHP out of it. Just have to dyno again. So, ~60-70 FWHP from the heads and intake. Not bad in my book for what they are and what they cost. Take a look at my average torque for the REAL story.

60--70HP from factory Ford heads and intake,I think thats good in anyone's book Dude,if you put in the rite cam you will be very close to a 100HP gain Not too shabby!!
