I have a 250 inline 6 that was pulled a few years ago to swap in a 350. The motor was running fine. Carb was just rebuilt. It's been stored inside since then.
I also have a 2 speed automatic Powerglide transmission that I just pulled from my 68 chevy pickup. It shifted fine and is in good condition. It's also stored inside.
I'll take $150. No shipping, but I will do what I can to make arrangements if you can work out something to come pick it up or have someone else pick it up. Both the transmission and motor were functioning well when pulled. Just decided to upgrade.
