You can adapt the LT1 converter to an LS, but not the other way around. LS is too long to retro fit it .

You can buy an aftermarket flex plate or drill the LS one to the early b.p. and extend the pilot to use an early converter with an LS .

so what is the difference of 4L60 and turbo 350 spline count
