1973 340 price check?

.060 is nothing to be scared of if there is enough metal on the thrust side of the bore. I have had a few. Sure u may not be able to bore it again but how many ppl will actually drive their cars enough to wear out the motor. I’ve had 318s bored .130 thou to 4.04 to use stock bore 340 pistons. Never once a heating problem. Ur motor is worth what someone is willing to pay u. Kim
