im going to have money to spend options?

ported pi head intake and comp cam 270 between 260-300 hp

03-04 pi motor comp cam 270 and nitrous 260-350 hp

im interested in cost ive heard wayyyy to many things bout pi head swaps costing between 500 to 2 grand

in ur opinion what would u do

If your doing nitrous I would do pi head and intake swap on your car.

Because by swapping to PI heads on. Non PI motor you actually raise your CR some

I have never understood why people dp the PI swaps, they raise the compression ratio, and there are better options out there.

Take a look at Airflow Research. They put in a set of there heads in a stock '95 GT and had gains of +40 rwhp, and +40 rwt

Also, for cams, I recomend custom grinds. Or check out Cushman Motorsports.

Probably because not many companie make heads for a mod motor and company that do are very expensive. A 95 is a 302

PI swaps can add 60 rwhp if tuned right.

It bumps the CR up by like ~.5

9.2 up to 10.7

i did the math when i did my swap, from what ive heard pi swaps love nitrous too

full bolt on pi swap with decent cams and longtubes back should be right around 300rwhp

i know pi swaps raise compresion but i dont know what a better and cheaper option would be there going to make the same numbers

school boy

personally, i wouldnt do the 270 cams unless you notch the pistons.

ive heard its between the 262 for street or the 270 the 270 is more mild sips more gas but its worth it can anyone give me a definite answer on how much it would be do a "head swap" ive heard and read anywhere from 500 to 2000 dollars

how much rwhp do u guys think a PI 4.6 with p&p heads and a 262 or 270 cam with minor bolt ons will make
