I have a 63 caddy that we are parting out, I dont know if the motor is stuck yet but does anyone think it's worth pulling. The car has been sitting for 20 years so the chances of it not being stuck is slim. I just don't want to waste my time pulling it if there are inherint problems to the caddy 390. Let me know what you guys think... Rick
While a '63 engine isn't the easiest to find speed equipment for, I certainly wouldn't throw one away if I had it. On the up side, '49-'62 intake manifolds will fit it, even though it looks like a totally different engine.
i'm not the '63 Cad expert,but i do know there are a lot of 1-year-only parts. save as much as you can.
