Since all LS1s make about 350 hp to the crank and most LT1s make 275-285... 65-75... Math r win

 

have you seen how restrictive stock heads are on an LT1??? letting that engine breathe will quite easily get up close to 340-350bhp. like grandpaswagon said, the LT4 (which was a mild HEAD AND INTAKE PACKAGE) made 330bhp stock, so what's so hard to believe about changing to a cylinder head that outflows the LT4 heads and getting close to LS1 power levels???

btw, the LS1 heads are not touch by god
