Well, it wasn't the torque converter spacing though I am now much happier with that even though Paul said it would be fine.

I guess now it is time to start into the valve train. I was told to run 20 thousandths clearance per set of rockers on the Harland Sharps for a street engine. And that's how I set it up. But I've also seen others say 15 thousandths. I think tomorrow I'll try to adjust the preload and the side clearance.
