Re: 1968 327 reubuild, vortec heads or not?
The motor was "supposedly" rebuilt sometime before I purchased it. The pistons were .30 over.
After taking it to the machine shop the said it needed to be bored .60 over because the was a ridge on top of the cylinders and some rust and pitting in the cylinders.
From what I can tell the motor was orginally out of a 1968 El Camino.
