trans adapters


Looking to see if anyone else has tried the following idea for marrying a Toploader to an early hemi. Since the smalll block Mopar bellhousing is almost (slight mod to holes and pins)a match to the early hemi's bolt pattern ...Why not use it instead of one of the adapter plates? I realize the flywheel will need to be a 10.5 model and you'll have to play around getting the ring gear and starter to match up but you will have eliminated that big chunk of aluminum around the rear of your engine. Using a Hyd bearing eliminates linkage problems.
The only big problem is getting the depth/indexing of the transmission to the crank.

Let's talk.............

I don't know if this will help all that much but...many years ago we mated a 354 to what we were told was a 273 bellhousing and 4 speed(which was already bolted to a 330 desoto when we got it). I don't recall any starter issues, just that we made some bellhousing bolts with a shoulder on them and it was OK. I do remember there was no adapter. Honestly, its so long ago I can't be more specific.

First, there is more than a slight difference in the dowel location between the early hemi and a late model bellhousing.

Second, the starter is what presents the problem, not the length of the trans input.
Because the starter bolts to the bellhousing in a fixed position, you would need to position the ring gear almost 1/2 inch closer to the rear of the block (toward the starter) to get the starter to engage.

here is a bellhousing which came from the usa it mates up with stock hemi adapter ,and top loader bolts stright up , stock hhemi flywheel needed to be machined down about 3/8" which also lightens it , i used a tilton hydraulic throw out clutch , there is no name or brand on this bellhousing as it came from a swap meet

Well the next way would be to find a Hemi bellhousing and adapt the trans there. You know that when 392s have the stock auto trans there is an adapter. Someone else will have to chime in on the other early Hemi engines.

You are correct. The crank flange sticks out to far. Use the adapter and save alot of headaches.

Thanks for the reply Jack. Appreciate/understand your position on just using the adapter an forgoing the headaches but I really don't want that chunk of aluminum on the back of my motor. Besides this is the type of thing I really enjoy about car building. Just can't believe I'm the first/only one to try it.
