Thread: 500 Caddy/G Body Swap

Tweet

Your right on the brakes Pat, I was running the 57-9 rears in the couple of V8 Pintos and the 77 Cobra II I built.....never had problems getting brake shoes, wheel cylinders bearing etc but finding brake drums was becoming almost impossible. I've kicked around the idea of doing a rear disc conversion, but the by the time you do that redrill the axels and rotors (or drums) and figure I'd still be running 50 year old axels, the drop in unit from QP starts to sound better.

Thanks for the mention of Sanderson rc, from what I've heard they just don't work in a G body though. What some guys are doing is buying the flanges and then modifying BB Chevy swap headers.

The most common exhaust on these seems to be passenger side El Do manifold and drivers side RWD 472 (which I happen to have). These engines still made 500 foot pounds of torque at the flywheel with manifolhids.....I think I can live with that (for now ).

the hooker comp bbc header s from a 66 chevelle will fit the g body with a small amout of work on the back tube but if the caddy is wider it going to be some work i like the 80 truck 9s axles are bigger drums and all parts are ez to find new and the axles have no window holes in them so you do not have to plug them to go to the 4 3/4 gm from the 4 1/2 on the old T bird i been there plugging all the window holes in the axle flange and re face them on the lathe and then drill out to 4.3/4 fun fun fun
