Bob, I'm sorry if you didn't like yours but I couldn't see how anyone wouldn't like one unless it was a hack job and your engine was worn out. I'll take you for a ride in a few and see what you think then.

I have about 10 - 4bts and 3 6bt's along with tons of parts. I install these in m715 army trucks. In fact i have everything needed to 'bolt" in a 6bt or 4bt in a chevy chassis with all cummins-gm parts( from adapter, starter, engine mounts, lord mounts, chassis mounts & all fasteners needed). Nothing fabed up i,ll sell if anybody wants to do this job correctly.

It looks like it has been a while, so is there any progress on the 71?

I'm doing one in a 67, so keep up posted !

Where did you get motor mounts?
