I am trying to trade/swap my original 350 and trans from my '68 Skylark for a late '60's to early '70's Big Block. I'm looking for a rebuildable Big Block and a 350/400 or 700R4 trans. This is my winter project... I won't let the 350 go until I have the 455 (having a 350 is still better than having nothing). The 350 was in the car and running great 2 weeks ago. It is absolutely complete and original and has 90K miles on it. I am outside of Detroit, Michigan and could travel 4-5 hours to meet. Let me know what you have and we can talk !! I am expecting trade + some $$ for a Big Block so don't think I am trying to trade even up (although that would be nice).
