97 GT Help

You would gain 40-50 hp from the head/cams/intake swap. What lincoln engine do you have? I thought they were all 4V...You may want to think of swaping the entire lincoln engine in and find a Cobra intake...a few here have done the 4V swap..

a headswap will give a a hp level higher than the 99-04 gt's. but if you have a complete 4v, you might as well just use that.

You'd gain about 45-50 crank hp. with the headswap. While you can use the 4v heads, it would be alot more involved than the PI swap.

yea the pi head swap will have you beatin up on some 99- ups

The PI cams and PI intake will give you just as much hp as doing the heads too. The heads might net you 5-10 more rwhp basically because you are increasing compression. NPI heads still will work pretty good and some people are putting down some great times with just PI cams and PI Intake.

The 4V head swap is so costly its not worth it. You need so many parts to make it work. This is some of what you will need to make the 4V headswap work and actually see some gains.
Heads
Intake
injectors
Crankshaft as the Cobras forged
Pistons for the compression bump you will need
Flywheel as the GT isnt the same bolt pattern as the cobras
Harness
Alternator
secondary drive chains
A tune

A 4V crate motor is cheaper as some have gotten themk for 1500.
