I'm thinking this is do-able. I have a GSR short block that i want to take the internals from and install in a LS block. Anyone done this before? It should make same power as a GSR, right? or if someone has a GSR Bare block they want to sell me, i would go that route.

 

yeah u can swap out the crank,rods and pistons but then u would have to do the ls/vtec conversion if ur gonna put the vtec head on it
