We have done several S10 to AD frame swaps and many S10's came with the 4.3 which was mated to a 700R4. The ones that decided to stay with the 4.3 rather than go the V8 route are very satisfied. I have noticed that the 0-60 times seem close between the 4.3 and a bone stock V8 but of course the V8 out pulls them after sixty or so.
