1964 Cadillac Coupe DeVille motor swap
 

I have a 1964 Cadillac Coupe DeVille with a 429, the motor has done nothing but given me problems, I'm about to pull it and go with a chevy 350 I purchased today. My questions are:

Will my existing tranny bolt up to the 350?
Can I purchase pre fabed motor mounts for the 350?
Has anyone ever done this swap?

Thanks for the help guys

You will need different trans or adapter. Chevy has it's own bell housing bolt pattern. Trans-Dapt probably made a kit years ago, they still make trans adapter. Frame and motor mounts for a 64 impala may work. Your car should have BOPK Turbo 400. I would try to find a chevy Turbo 400 trans that should minimize extra fab work. I would install transmission first if using thm 400, bolt engine to it , and then layout mounts and brackets for engine. If using different trans you will have some additional fab work to do. I have never done this application, but its a small engine in a big engine compartment. It should not be too bad. You might want a welder available to help with fab work. Good Luck
