Depends on fuel, tune, where in the island efficiency range the blower is running and how efficient the intercooler is.

depends on the setup i ran about the same compression as you i had crap *** gt40 heads a tfs street heat intake and a s trim at 16 psi non intercooled at 22 total timing at 6000 rpm made 474 to the rear wheels at 12psi and 36 total timing it was making according to mph and et around 650 at the crank which woulda been like 540 at the rear wheels.

So with the right heads, cam, etc, setup can i get that kind of HP from a centrifugal style supercharger or would I have to go to the roots style, or does it make a difference?
Also... isnt running too much boost bad for the block anyways or does the concern have to do with strictly the amount of hp? would it not be safer for the block to go with a stroker kit and put a 6-8psi or lower s/c on? or am i just completely misinformed?

there is going to be a ton of different view points i would say cylinder pressure on a stock block can be a issue and forced induction tends to be very different from an N/A motor total compression not static compression is very different with a forced induction style motor. either way its really a difficult issue to say which is better. It would probably survive better at the 6-8psi range

save up the extra $700 and get a DART SHP block honestly, then you wont have to worry about the stock block any more, itll come down to fuel system limitations and tuning issues...

DART + 363 + centri = sexxxxxxxxxxxxxx
