Thanks in advance.
NO WAY
it's impossible because LS engines comes with newer crankcase, combustion chamber and sleeve.........the cranck case is higher, and to make the combustion chamber and sleeve fit the new cranckcase then they both are longer than they were in previous engines......
only carburettor, backplate, head, bearings, shaft, conrod and piston are the same.........
