hey ron, I built the motor. The rebuild was a tear down and inspect and reseal. the short end of the story is I bought it from a guy in north ridgeville he went to a 347. He had rebuilt it about 30-40k ago. I tore it all down to put in new parts and put on heads,timing chain,cam and etc. So I know everything is good, the motor speaks for itself. No leaks and no problems. The motor has a stock tb and injectors. if you want it in your car you could have brian tune it but thats not needed really.
