What you have is an AMC

"Jeff
What you have is an AMC 327 ci engine most likely with a carter 4 barrell carb. The manifold probably is the original one. AMC motors made this engine for Gray Marine. The eng. tags from AMC were mounted on the gen. or alt. bracket and most likely are missing. Dont concern yourself with this. Its a very strong motor, I am tearing one down right now. The #s on your exhaust manifold are the date that they were replaced. They are known for rusted out Hope this info helps. Pat"

Thanks for the informa

Thanks for the information. Former owner said it was a 327 but I couldn't verify that from the Service Manual he gave me. It has a Holly carb and the firing order on the intake does not match the dist. guess that doesn't matter.
Are you using a shop manual for your rebuild...if so where did you get it? I want to rebuild too and have many questions. Any sources you could share would be appreciated.
Thanks
