I sold my 68 coupe a few weeks ago and I have been regretting it ever since. But I came across another Camaro that is in even better condition than the one I just sold. The car has no engine but I think it was originally a 6 cylinder car. If I buy it and want to change over to a 327 or 350. What changes will I have to make? Do I have to change the radiator? Wiring harness? Motor mounts? Please help me on this one guys. Thank you.
