Ok i have been wanting this for quite a while and finally about to come thru i am doing the pi-swap on my 98 GT, on the pi heads i sent them to get p&p, new valve spring upgrade from trickflow, new valves, stage 2 supercharger cam's by Crower, and a paxton novi 1000 with stock pulley, i already have 75mm throtle body & intake plenum by trickflow, catless x-pipe. Now just with this and a tune it dynoed at 215whp and 289ft/tq...

stock bottom end do you guys think my block will hold this it has 113k

im not really sure but i tihnk the PI heads increase your compression. compression and a supercharger dont mix.

They dont raise them enough to cause any issues.

so does anyone have an idea of what hp will i be looking at, im hoping to see 400rwhp...

i make close to 300rwhp with my setup and its only tuned for 87/89 and iits very conservative they didnt even touch the timing. He said after i get the 4.10's in to bring it back and get the 93 tune and ill break 300rwhp. So you should be close to 400rwhp with a blower. But watch how much boost you push with the higher compression.

With the p&p PI heads, intake, cams and supercharger you should see 400-420 rwhp. You need to make sure you have a good tune and may even want the tuner to back off the timing a little. While the additional compression doesn't prevent you from running a supercharger, it does increase the chances of detonation.
