im pretty happy with the results considering the shop temp was 93* with 100% humidity! this was the 8th pull out of 10, so it was pretty hot, it makes power to 6700, the starts to slightly nose over after that! and it gained a ton of low end tq with the MHS camswill be going to the track next week! hoping for 12.teens....
STD numbers were 336rwhp/312rwtq
I know this is an old thread, I was just browsing the net looking for more info on npi ported/polished heads, with pi intake & cams and I found this. I think these number are impressive. I have an 97 gt with the basics; k&n cia, bbk 70mm throttle, upper plenum, bbk aluminum pulley kit, bbk shorties (will be switching to long tubes), 2500 stall, and bama sct tune. I have pi cams and pi intake that are not installed at the moment, an I am looking to have my npi head rebuilt p&p. Could you possibly post your you had at the time, am just taking notes, I am also planning on procharging it.
