I am going to do a PI swap on my 96 GT. I might get the heads ported but not sure yet. Just wanting to know what cams would be the best to go with? Thanks.
I agree with chris, also look at NPI grinds. A car at moduladep0t made 295 with NPI comp 268's with stock PI heads, not ported. Ill be going with 268's or a custom grind. Ive been reccomended having these cams custom ground for my na car. The specs fit what I want..
"Greenbird--
Advertised (.006" lift) intake duration: 258
Advertised (.006" lift) exhaust duration: 264
Intake duration @.050" lift: 222
Exhaust duration at .050" lift: 226
Max intake lift: .560"
Max exhaust lift: .550"
Lobe separation angle: 110
This cam should perform like stock below 3000 rpms. After that you will start to see gains, and you should see a gain of about 20rwhp at peak. That's quite a bit considering your staying within the stock RPM band.
