Do you mean what I wrote? Show me someone at the 400 RWHP mark with the basic H/C/I or stock motor w/ a supercharger on it. I never said the stock block wont make over 300 Im saying the stock motor w/a S/C or H/C/I set up will net you about 300 (give or take) each so why not spend less and do it with the H/C/I b/c you wont need to up grade injectors and the pump so over all its cheaper to get the same power. Maybe 24LB injectors but those are much cheaper then 42's which you would need with boost.
