I have 2 351C blocks from 1973 mustangs that are .30 overbore, I need to do a rebuild as these came out of cars and I know little of thier mileage or history. If possible I will be able to just hone and use .30 pistons again. BUT my luck is never that good. I would like to have them sonic tested for cylinder thickness but dont know where to get it done or how much it cost. On an average 351C block is a .40 overbore usually fine? Also how would you go about checking for non obvious cracks in the block if it is already out of the car and disassembled. I didnt notice any mixed fluids when tearing them down.
Any advice or comments would be great.
