Re: LS1 Internals!
LS1 engines and SBCs are too different. Most parts won't interchange.

Re: LS1 Internals!
Don't know what you are calling an internal exactly, are we talking about rotating assembly or everything within the block? Either way nothing from a LS1 is really interchangeable, the LS1 and a 350 have different bores so pistons and rings are useless. Cam and crank aren't interchangeable.

Rod bearings and roller lifters are the only LS1 parts that will fit in a Gen I/II SBC.
