Re: Complete motor and drive swapping ??
Nope. Too many things different. Just for starters, the gear ratio would be wrong, the exhaust tube attached to the gimbal housing would have to be replaced with one for a V8. The bolt patters may not line up. Then you have different motor mounts, wrong exhaust manifolds and risers, possibly no stringers to mount the V8 on. The motor box may not be big enough to go over the engine, no flywheel housing for the V8, or coupler, etc. That's just the most obvious problems.
