LS1 Manifold

I was wondering if stock manifolds of a 2001 ls1 will fit on a 1981 350.

No, the LS1 and the standard sbc share very few similarities. LS1's have exhaust ports spaced out like a BBC. They will not fit on any standard gen 1 sbc.

actually I think the LS1 shares nothing with the other two gen small blocks...right? Other than the bore size or stroke, and obviously the cube size....but isnt it like a 346? I think he'd be better off with the LT1 intake or TPIS big mouth base......
