Default Blown motor in my 86

A couple of weeks ago my engine heater plug came out causing the motor to majorly over heat by the time the warning lights came on ( coolant temp went to 299 and oil went to 350) . The engine shut down and I towed the car home. The motor still runs but smokes like a freight train, and sounds like hell. My question to all of you who have rebuilt a vette motor is how much can I bore out the cylinders without causing any problems. If it has to be rebuilt, it's going to be better than it was as a stock motor. Also any suggestions on where to buy parts online to rebuild this motor.

Thanks for all your help
Steve

think about this: ZZ4.

A crate motor will give you tons of what you want, with a nice warrantee...

There is also a chance the block was hurt when it blew, you may want to pull and confirm what you are dealing with before committing to a rebuild.
