sounds very mechanical. Did you try it without the converter connected?

TedRamAirII,

With Paul finding the bad distributor bushing after we located the witness marks are the oil pump shaft, we thought for sure that was the issue. This motor was on the dyno a month ago and it still has the same noise as before. We've done the wooden stick, long screwdriver and even a mechanics stethoscope. We thought we had a signature at the distributor. Nobody can understand why the motor is reported to have been running good on the dyno but yet bad in the car. We didn't touch the timing or adjust the carb prior the starting the car. Before I sent the motor back, we ran it without the belts..noise was still present. The balancer was torqued by Paul so I'm positive it's correct. We will check it but the noise has always remained the same. Pulley bolts were tight and we didnt get a signature from the fuel pump. We even ran the motor with the fuel from just the bowls and the knocking never left. We felt the dipstick and it was fine...no vibration or marks on the dipstick. As for the distributor...it was reported that the bushing went bad on the MSD ready to run distributor. I've done months of research to find another case of an MSD distributor bushing going bad and I couldn't find another complaint. Distributor cap was fine. Paul had it in his hands when he discoverd the bad bushing.

Is it even possible that the distributor was severely damaged when the motor blew up on the dyno because the pickup tube fell into the pan? What exactly happens? Is that a violent failure or does the motor just die a slow death?

I agree with TedRamAir. Get your hands on the motor to feel for the noise. I would get the car in the air enough to get under it. On stands or ramps. A lift would be best. Take all the belts off so there are no external accessories being driven. You wont run it long enough to overheat it. Get under it and put your hands on the pan. Use some sort of stethoscope tool to listen for it.
You running 1.5 rockers or 1.65?
