My plans are I have a 54 belair i wante dto replace the 235 with a 68 chevy 250 and a turbo 350.I thought it was a esay swap.Then found ou tabout the length difference in motors.I already swapped out rear end for open drive.The price for rebuild on 235 is between 1400 and 2000 dollars.I bought a 250 and trans out of a 68 camaro for 300. 30,000 mile son both.Now weighing my options.i was hoping the exchange would be a easy drop in.I was hoping I could talk to people who have made the switch to see what problems they incurred and if it was worth it.
