""This was run all the time behind an automatic? If so you could have a ballooned converter. Did you run nitrous?""

This engine has always run in front of a 727. But I have had three different converters in it over the last 22 years since this motor was last rebuilt. The current converter I was able to spin with no clearance issues to the flex plate. I will be checking the clearance again once the engine goes back in.

No on the nitrous.

Thanks!
