Maybe my batteries are old but I swear I used to crank faster. Going from stock 454 I would guess like 8:1 to a 9.5:1 502. Is this the reason for those mini-high torque starters?

It all adds up, new rings, tight tolerances, etc. check for corrosion on your terminals and make sure everything is tight.

do you have a minimum of 4 gauge battery cables? or did you keep the original 6 gauge cable?
