My son and I are rebuilding a 68 conv. A 1976 400 engine came with the car but not in it. We also received a 400 turbo tran. My question is would I be better off (cost wise) buying a crate engine vs. having the 400 rebuilt? What about the tranny? Checker sells 400 crates for $1500. The tranny can be rebuilt for $800. We're just looking to have a 400 Auto in the car that runs good and dont need a performance race engine. Can someone give good advice on which way to go? Any other sources to buy a crate from? Thanks!
