My 98's LS1 spun the rod bearing. I looked around and bought one of MIZFIT Motorsports 2001 Vette crate motors. I was going to take the Torquer V2,pushrods,spgs,tit. retainers,and crane double roller gear set off the 98 and transplant it all over to the new motor. Should I expect any significant HP gains this. I know the 98 Ls1 was rated at 305hp and this crate motor is rated at 350 hp from GM.I know they used the LS6 block on these motors. I was wondering if their was any real difference in the heads.I know the Ls6 intake is worth at least 20 hp anyway.

The heads flow better and the intake flows better. I'd say about 20 hp is possible. There's a sticky somewhere that tells all the differences.

Well, that is flywheel horsepower. You will see around 375-390 most likely with that cam.
