...Putting a different gasoline engine in a GMC using the THM-425 (with the exception of the Cadillac) seems to me an exercise in 'can I do it'. More power to those who do. But it does nothing for the coach in my uses.

I'd agree and I'm firmly in the 'just because I can camp...' FIRMLY! A different engine with the same tranny just isn't feasible as long as we can still get parts and cores for the Olds/Caddys.

I have a fresh 500 sitting at John Beavers shop waiting run-in. It's going in the car hauler. If I could find a good deal on a modern 5 speed OD tranny and transfer case I'd see if I could adapt it to the 1 ton hubs using a generic GM differential similar to what Hal StClair did. I think it would be doable and we'd have a jillion rear end ratios available for cheap. There are no shortages of Caddy cores. I'd consider doing this...'just because I can...'Smile Of course if I can adapt a Caddy to a new tranny, adapting a LS motor would be a snap. Plus I don't have to worry about steps or hatches but I'd try to work within those constraints just because it would be good to know.

I'm also planning on installing a Chevy 1 ton front end but will make new control arm mounts and use the stock control arms.

I'm going to pull the subframe from the parts coach that will become the car hauler and do all this fab work on my welding table so I can jig everything up.

I wish I lived near to some of you guys. This would be a lot more fun working with someone.

Anyone got a 5 speed auto and transfer case they want to swap for a good Honda EV6010?
