65 Chevy ll transmission upgrade

[ridesafely]

Is it possible to install an automatic transmission in a Chevyll 230 eng with overdrive? Just curious.

yes with the proper adaptor it is possible,

Adapter??? A 700R4 or a 200 4R will basically bolt in. The 700 will require some more work, but both give a lower first gear ratio and 4th gear over drive ratio. Cross member needs to be replaced and drive shaft shortened. Transmission will bolt to the engine without an adapter.

Thanks for the correction, I was thinking Pontiac.

No problem, I was thinking of doing the same. Have a 72 Chevelle with a 250. Just picked up a 700R4 and 3.73 12 bolt. May run it until a V8 can be built.

That 3.73 will make a very noticeable improvement!

Sure will there is a 2.56 geared 10 bolt in it right now
