Thank you for the feedback! I bought the car 3 years ago and we've spent a lot trying to make it look good. The engine ran excellent with plenty of power and A833 4 speed, but developed a rattle in the lower end so I decided to take it out and go through it. The engine has hydraulic lifers and with the intake set up being different, I figured I need to know what I'm working with before going forward. It has an aftermarket Edelbrock carburetor. The head castings are 2465315-2and block is 2806030-273-7 , are these correct for the 65 year?
