Technical 1939 cadillac engine tranny question?

Will a 39 caddy c8 bolt up to a modern auto transmission?

 

"Will a 39 caddy c8 bolt up to a modern auto transmission?"

Hard to get those C8s bolted up to anything!

 

But the v8's will with some work.

 

not without some sort of adapter plate

 

On the FlatCad, we did a lot of work with our custom crankshaft to mimic a FE Ford rear crank flange - and then worked with Wilcap (Pat McGuire) to setup an adapter (all working from the same dimensions). I would call Wilcap - they are the best folks to deal with the oddball stuff and have made a lot of adapters for the most goofy of shit (which a Flathead Cadillac is the founding father!). My guess is that it is definitely possible - with a custom trans adapter, custom flywheel and the associated $$$ - anything can be made to work! (Plus - Pat has the geometry/CAD designs that you need to do the work!).

 

Bendtsen’s do a kit for 346 flatheads.

 

so what will work?

 

There is a thread on here somewhere about fabracating a bellhousing for a flat cad. something like "caveman bellhousing" do a search

Bentsen's do a lot of odd ball stuff, a reputable company and great to work with, recommended!!
