I've got two cast iron powerglides for sale. One from a 57 chevy 265 that was in a time capsule roadster that was put away from 1967 to 2018. I replaced the running gear with a flathead. The second powerglide is from a current project which is a restored 57 chevy convertible with a 283 that had an under hood and interior fire. I would bet both transmissions are good but that's just an opinion. I'm pricing them super cheap so I cane find them a good home. $100 for both!
