Performance modifications
I have a 2003 screw with the 4.6L 2valve. Im looking at possibly replacing the intake manifold cams and porting the heads. Any info on where i can get an intake manifold? I was looking at trickflo but they dont list their 4.6L 2valve intake as only fitting mustangs. Anyone know of it fits or anyone else that makes them?
To my knowledge there is no aftermarket f150 performance intake manifold. The mustang one is clocked to the 9:00 position not the 6:00 like our trucks. If you were to switch you would need to completely change your air intake and throttlebody position, as well as loose quite a bit of low end torque.
All I did with mine sofar is, fully forged bottom end, pi heads (gasket matched), about 12.5ish:1 compression, ported the intake, ported the plenum, bbk 75mm tb, aem cai with a dry filter, custom tuned, madfan, and a wet kit.
It runs good for what it is but if I were to do it all over again I would have done it at about 9.5:1 and put some boost to it.
