The engine is a Thunderbird 390 with the Ford 4 barrel. There have been no modifications done. No headers, no MSD, no fancy valve covers. She is a pretty, bone-stock, 4 door, Texas-born Hardtop Galaxie XL with buckets, console and no B pillars. And no rust. (Ask for pictures if anyone is interested...).
Again - COULD it be the transmission or convertor?
The problem is there in gear. It seems to me that if there was a faulty convertor, the problem would show up once the convertor was called to service. Could it be acting up so much as to d-r-a-g the power out of the engine?

Thoughts?

I have been wrong before, I assure you. But I do not want to chase a goose if I am very wrong about the convertor. That is a LOT of work that I am not really set up to perform.
