Bruce Nunnally Posted October 27, 2020 Report Share Posted October 27, 2020 Received this query in email: I have a 1961 caddy series 62 with a GM crate 502 and a GM 700R4 automatic overdrive transmission. I would like to get some info on swapping out that engine for something with a little better mpg. I have the original front end which was recently replaced with factory parts. Can you suggest a engine that would fit? I bought it as a retirement gift and I drive it most every day. Any suggestions would be greatly appreciated.
