Getting ready to pull out the motor and do a rebuild. .30 over, comp cam, performer intake, and thought about rebuilding original carb if it is a 600.

cleaned off tag enough to get numbers and its a 480 cfm...... What if I got a jet kit and rebuilt it to a 600. Good idea?

Those cars never came with a Holley carburetor from the factory. Original equipment would've been an Autolite unit (4100 or 4300, though I'm probably a little off on the numbers) that flowed around 480-500 cfm.

You are correct. It is a autolite 480. Would you go with a larger 600 or stick with the 480? Going .30 over, comp cam, and new intake.
