So my stang is at the shop and discovered my mani is leaking. Figured now is a good time for a pi swap. I read that getting just IM and cams are better than getting heads with it too because you can port the npi heads for better flow than the pi heads. I was able to find a full IM kit from summit racing, but where do I get the cams from? Or is it better to do like a stage cam? I'm also trying not to spend massive amounts of money, and need the parts express shipped. Also do I NEED a tune for this?
Intake manifold and cams are not better than getting heads only if you want such little gain in power.
Trick Flow Heads are the way to go and with a good flowing manifold will give you big power.
Porting stock heads are a waste of time and still don't out perform non ported Trick Flows Twisted Wedge heads.
If you ever decide in doing the swap, this is the way to go.
Go to a junkyard and pull a set of the PI heads and intake. They've been out for so long that there are tons of cars out there with them now. Cams may be an issue since you may be pulling them off of a family sedan or truck and would need to swap an acceptable cam into the heads.
