Differential


As I sit here I start wondering about the differential in these cars, I know mine is a posi however what is the differential? they have a removable carrier as far as I can see, like ford 9 inch style, anyone got any info? how strong can these stock rearends be built? is it a full floater? semi? just curious.

Yes they do have the "Pumpkin" pot like a Ford. Not the strongest rear end & axle & brgs are a weak link. Interchange from 55 to 64 full size Chevy & Cdn. Pontiac!! They will take some HP & Minor abuse, I snapped a pinion off a 55 way back when due to too much torque & "side steppin the clutch" at "insane " RPM!!!!

Last year was '64. They are semi-floaters. Early straight axle Corvettes also used the same center section. I think it was Moroso that sold a Brute Strength center section for drag racing since the combination of high horsepower and sticky tires would expose the weakness in those rears.

so is it better to beef up the center section? narrow a 9" or narrow 10bolt?

mine came stock with 17 spline axels

The differential is the weak link in these cars. For high HP you might want to consider one of the options suggested.
