By the time it got to me it had the 340 and B body 8-3/4 swapped in by the owner I bought it from... he retained the 727 that was behind the 318. Additionally it has not been a simple fix at any time. Everything that could be worn out is, assembled wrong check, yup lots of rework. I call it good parts, good intentions, unfortunate execution. He was great guy, not really his fault he kept running into inability to afford fixing it up. After 50 years its anything you touch on the car you have to ask "how deep does this issue im trying to fix go?" The answer is thousands of dollars deep lol.
