I've never seen just an adaptor per se, but Lakewood used to make a scattershield that would accept one and may still.
This would be the simplest solution. The only issue I can see is if the input shaft length becomes and issue.
Here's a guy who made a housing to adapt a top loader to a Chevy...Don't freak out over the impressive but off topic drag car...Scroll way down for the clutch housing fabrication https://grannys.tripod.com/20102.html
I have a couple of McLeod housings, they are Chevy/Chevy, Chevy/Ford. Don't know if they still make them, however they re-certified one for me recently.
MeanGene427, have you ever owned a vehicle/w a Muncie transmission? I have, an M22 "Rockcrusher" behind an L78 396. It did not go "boom," LOL. Ford transmissions don't fail, right? Any transmission, regardless of make, regardless of application, can fail. The AOD in my 5.0 Mustang had to be rebuilt under warranty. Isn't that a Ford transmission? Nevertheless, my 55 Tbird, which has been in the family for 50 years, is getting a Ford C4 in place of the Fordomatic, while the Ford 292 Y-block remains.
Thinking that a Munchie is a strong trans is the height of being Chebbrainwashed lol- I made a lot of money in the old days selling Munchies, sometimes repeat customers. You had the strongest version, and had good luck- emphasis on "luck". Munchies go for a premium these days just because few survived. Lots of toploaders still around
I could be 'mean' and point out it took GM three tries to get the Muncie 'right'. The M-22 may have been built from embarrassment as the Chevy racers were converting to Ford toploaders almost wholesale until the M-22 appeared in '67, which is why those Ford-pattern scattershields exist. Or that Pontiac and Olds bought Ford 3.03 toploader three speeds as the base manual trans in the early GTOs and 442s as they didn't trust the GM versions. The mighty TKO and most 4-speed race manuals are all based on the Ford trans design... But I'm not trying to be mean....
So, why did OT Pontiac Firebird come from the factory with Ford 3 speed top loader transmission? Paul Harvey once asked "How do you keep your GM car all GM when it says FoMoCo on the transmission?" (Maybe not exact quote, but very close.) Sorry, should have read above post more closely. Lol.
I thought for sure Trans Dapt made one back in the day and looked at my catalogs. Nope. The Ford trans showed for their adapters were 1949 to 1964 and were most likely T10. My latest catalog is 1968..maybe Trans Dapt made one later, but I doubt it. Your best bet is a scattershield as mentioned above..
I have an Offenhauser adapter on my car. However, the transmission is one of those Ford top loader 3 speed and overdrive units without the dual bolt patterns so I had to drill two new mounting holes on the transmission. I purchased it from Speedway.
One obvious reason why there isn't very many adaptors to put a top loader behind a Chevy is because they shift like molasses in the winter.
