L92/LS3 issues.

[ScottT]

i converted the motor over to all ls3 with aftermarket cam, springs, moroso pump, slp underdrivve harmoic balancer, headers, and got an ls3 intake and use rthe l92 stick one. My question is would it be worth getting a used fast 92mm for 500-600? Also has anyone found out how much hp is gained by porting and polishing heads and matching to intake. Also will the ti push rods from an ls7 fit in y engine? And any advice on pistons and con rods, and rockers would be great. Im 23 and in colllege so no time for research and a budget
