B20 Swap Incoming!
Posted by: B20Vair ()
Date: February 19, 2020 09:52AM

Hello all, new Corvair owner here. I got a 65 Monza with no engine, original 2 speed powerglide, pretty nice body, and a great interior. My plan is to put a B20 Honda engine into the rear since it also turns counterclockwise. At the moment, however, I’m having trouble trying to figure out what exactly I’d need to mount the B20 to the powerglide. That being said, I’m also a little confused on how exactly the input/output from the engine to the trans and then to the diff. Any help would be greatly appreciated, I’d like to get this baby road-worthy as soon as possible.

There was a guy on the other corvair forum that did a b swap. might want to go dig up his threads for ideas and inspiration.

are you set on using the 2 speed auto?
i would think a 4 speed would really make that a blast to drive.

Welcome to the CCF! You are in luck! There are other Vair owners in El Paso!!

And it's been done before!

All the other pics are gone... but I'm sure Ted Brown still has them and remembers what it took to mate to a PG.

The "other Forum" don't Google... you never find it!! is the and the guy there used the Corvair 4 speed..and regretted it.. It's in the Engine swaps section there.

This link should take you to a number of Honda powered Corvair videos. They are rather short and not descriptive.

Honda Powered Corvair

This is the link to the Corvair Forum regarding the B20 powered Corvair.
