Okay, got my 1974 chevy bread van with the 4bt/400turbo. I was going
to just swap the motor and adapter into my 1977 one ton crew cab 4WD
that has an existing 400turbo. But now am thinking about retrofitting
a 4spd stick/transfer case and putting a brownie auxillary tranny
behind that so that i can under/direct/overdrive in any gear when I am
in 2WD mode.

Questions:

do the toadstool motormounts cross over or do i just bolt up to the
existing motormounts in the 4WD?

Can I use the same starter that comes with the auto when i go to
manual?

Does the flywheel just bolt on in place of the flexplate?

I have done plenty of inline 6 to v8 swaps and auto to manual swaps,
in chevys so I am fairly familiar with the swap process but haven't
done one of these. Am I expecting it to be too simple?

Thanks in advance. Warmest regards.

you can use any motor mounts you like, but you will need to do the welding since no one makes pre-made swap mounts.

You will need a the GM style trans adapter (you already have it) but you also need the GM style manual flywheel. The starter and starter spacer that came with the 4BT/TH400 will be re-used.

Are you the same guy I gave the flywheel link to on the yahoo group?

Yep. I looked at the links you indicated but just wasn't clear on some of these issues. This forum seems to have more activity. And, I guess I was hoping I could transfer the toadstools from the GM van to the truck. Thanks again! Regards, Tad

People have done swaps with each style, so I guess you take your pick.
No side-by-side comparisons, though.

I believe the chevy mounts are the same for all gas and diesel v8's
