GT-40P Heads on finally

93NOTCHLX · 09-07-2001, 09:09 PM

My P heads, E-cam, and explorer intake are on. I picked .6 ET and 4.1MPH. The T-Body, H-pipe and cat-back is stock so I guess that is choking me. Only made a total of seven passes in the car, so hopefully when I learn to drive it better and get an exhaust I'll shave off some more. Just info for anyone who is considering P-heads - the money you save over aluminums can be put toward cam and intake if you are on a tight budget.

i think with exhaust/tb/maf(is that still stock?) and drivinging, you can probably pick up .4. sounds good, is that your new time in your sig?

93NOTCHLX · 09-08-2001, 08:33 AM

Yes, that is the new time. I sure would like to run about 13.70's.

What headers are you running with that combo?

93NOTCHLX · 09-09-2001, 08:24 AM

I'm running the FMS stainless headers that I had jet hot coated. They fit very nice, easy to install and plenty of clearance for plug wires.

What gear ratio are you running?

93NOTCHLX · 09-10-2001, 07:57 AM

Nice. Are the headers Gt-40p specific? I've heard the factory HO headers will fit on the GT-40p's, but nothing short of the GT-40p MAC headers fit otherwise.

Maybe it is elevation, but i am running consistent 14.0's @98 on stock heads and cam.

Then again, i pulled my swaybar off, and have a brand new track to run on, is your car a 5spd?

im thinking about p's and b-cam, but want to make sure im gonna be well in the low 13's before i spend$

Unit -

I'm running a set of Motorsport headers that are GT-40p specific. They were a bit pricey, about $250.
