what is a good reasonable price for some used pi heads and intake?

 

If all you're looking for are stock heads. You should be able to pick them
up for around $300.00 I've saw lots of them around hat price.

 

jegs has a pair of pretty good stock pi heads. just make sure you get the head changing gaskets and pi intake manifold too

 

I paid 400 on e-bay for the heads and intake but I'm getting a dif manifold, typhoon

 

how much faster will it make the stang

 

Full PI SWAP usually around 5 or so more HP than a stock PI car.

 

I'm in the process of doing the PI Swap on my 96 GT, but i'm hand porting/polishing the heads, and adding some Cushman II cams. If you do the swap on a 96-98 you should get up to 260 without aftermarket cams and a port and polish job. If you do cams and p/p job you could see around 300-310 if your lucky with a dyno tune. Good luck I picked mine up on Ebay for 399 with Heads/cams/intake manifold/tb/upper intake/iac valve/tps sensor, and all of the bolts. Ebay is the way to go.

Thanks,
