just bought a 400 slabby, do slabby 750 engines bolt in or do you need engine mounts making up? also do gk71b parts sell easy?

Ermm, not sure, but why not just buy a slabby?

The 750 motor dont fit in the gk76 so at a guess id say no.

can anyone confirm if its a case of getting the bottom rail modded to fit the 750 motor? would fitting bottom rails from a 750 be a better idea? could just stick the engine in a 750 slabby frame but thats easy!

Theres a guy did a 750 gk76a on another site with pictures and measurements, sure theres a link from here somewhere abouts. It showed how different the mounts were and it looked a fair project and im speacking as i qualified engineer.
