Be careful here, ATI claims x amount of horsepower but it really depends on how your heads flow, Remember the number given is on STOCK heads, I have a 383 LT1 with heavily ported LT4 heads, then most I could get was in the low 500 RWHP range and was over spinning the blower, went to the D1 and made 648 RWHP on Pump gas and 722 RWHP on fast gas...if you are looking for mid 400's RWHP range then this might be ok, though the P600 is an older style blower, I believe the newer setup is the P1sc...

i had a old school p600b i got from my uncle way back in the 90's
for a sbc,
uncle had it on a 400 sbc, p600b is supposed to support 700 bhp
but i dont think the 400 was anywhere near 700hp,
more like 500-550 with the procharger "custom" carburator that came with it.
