Yes.....but with provisions.

The SB 400ci crank is the crank you would use to 'stroke' a 350ci to 377ci (383ci w/.030" overbore).

If you put the 400ci crank (3.75") into a 350ci (3.48") you would need to get new pistons spec'ed for the increased crank stroke.

ALSO, the crank from the 400ci SB has a 2-piece main seal where-as the LT1 has a 1-piece......you would need a 2-piece to 1-piece adaptor.....available through GMPP.

I would be a bit easier to just get a 1-piece 3.75" crank......available almost anywhere fine engine parts are sold .
