I have an 86GT motor in my car now with only 45K on it. I was going to swap it out for a fresh built 306 short block that I got some time ago, but have second thoughts about going to the trouble to swap-out because I can't figure out if it is internally balanced or what - it shows signs of crank lightening.... besides that, it's pre-roller so a reduced base circle came must be used to go roller - might not use it at all, which leads to my question in the thread:
My stock motor is an 1986 still in the car. I was thinking of just using this motor to slap my new AFR165's on, but was concerned about any valve clearance issues as I heard some time back that the 1986 motor has flattop pistons and needed valve clearancing. (True or False?)
I really would like to accomplish this install, and any piston mods, without pulling the motor. Is this possible?
