Gaston Rey Posted November 26, 2004 Share Posted November 26, 2004 Hello everyone. I'm new to the forums.I just purchased a 1956 Cadillac Coupe 6237 and the engine is missing the cylinder heads. I believe the car has a 365ci engine form the factory, but some people had told me that the 331, 365 & 390 use the same heads.Does anyone know where can I find some used or rebuilt heads?Also, Is the hydra-matic transmision rebuildable? Are there parts still available for them?Thank you all for you help!!!I love this forums!!! Link to comment Share on other sites More sharing options...
jaxops Posted November 30, 2004 Share Posted November 30, 2004 Gaston, I have a 56 Cadillac Series 75. I purchased all of my enigne parts including new pistons, shafts, bearings, etc from Cooper's Vintage, http://www.coopersvintage.com/Mr. Cooper is very affable and willing to help, and ships very quickly if you ask him to. I have had him send parts right to the shop rebuilding my engine also. Others sources are Caddy Daddy, and Kanter for some parts. Kanter takes 2 weeks to process everything, so if you need it now, they can't always come through but their return policy is very good. Yes, your engine should be a 365 cu inch and should have a 4bbl carburetor either a Carter or Rochester.As an aside, I recommend Diamondback Tires for WWW steel belted radials if you need them. Good luck. Let me know if I can be of help. I also get parts from the car that I upgrade, so let me know if you're missing any trim. Right now I have a spare front hood lip aluminum piece.Sincerely,Mark Monaghan jaxops@bellatlantic.net Link to comment Share on other sites More sharing options...
