RE: Highway race with gears ped me off
How about doing the PI swap, and just f-ck the bullsh-t??
If you're that addament about porting/polishing heads, pick up a set of used heads from a junkyard/ebay/other source and have a machine shop port/polish/rebuild.. That way, when you do your swap, it saves you a boat load of down time.. It's only a little bit more work to get the heads off at that point in the swap...

no i dont have a pi swap i thought maybe because of the gear ratio is why i lost that race since we were already at 70 mph

The swap here isn't just the heads, it involves the cams and intake also. You can make some considerable power gains with the combination of PI heads, PI intake, and appropriate cams. A friend of mine has a 98 with the FRPP PI heads, PI intake, VT stage 2 cams, + 100 shot of nitrous. I don't know his dyno numbers, but a little while ago he ran a 13.12 to beat an 01 (I think it was an 01) trans am ws6 at Milan (trans am put down 13.4). He's got some other things done to his car (pulleys, plug wires, some suspension, etc.)... But I'm just sayin', you could save up and go big later on:-)
To answer the original question, I think a P&P on the NPI heads will run you like 15 rwhp.

i want to save for the swap but whould it be cheaper to take the heads on my car and have them ported and polished or do the swap, as for the race at 70-75 with my gears iam already at 2500rpm i have no pull left so the caddy left me

RE: Highway race with gears ped me off
The fact that you raced from a roll in a NPI GT shows you don't know much about your car. NPI's choke over 4500rpms due to a restrictive intake and low lift cams. You were dead in the water before you even hit the gas You can get your stock heads ported and get good gains but to have them done right by a good shop will cost alot of money. If your on a budget just get a complete PI swap from www.parkwayperformance.com That will wake your pig up big time!

Hey, droptop, what about cams for the PI swap? What kind of gains are there to be had with PI heads and intake + VT stage 2 or Compcams XE262AH (for example)... I'm tryin' to do some research here, seems like you are one of the most knowledgeable guys here, specially for the 4.6 SN95's...
