I will add that my senses were on high alert the whole time, waiting to hear/feel/smell the 1st hint of the crankshaft snapping in half, the ring and pinion exploding, the oil turning to jelly or some other catastrophic event ending the fun and games. Nary a hiccup.......
Not sure if it counts, but the 82 GMC pickup truck that I had with the 1973, non rebuilt 400, made the 700 mile round trip to/from New Orleans and an additional 200 miles of in town driving during the month I was there. Made 15 MPG with a TH-400 and 3.23 gears.

The entire trip I was thinking about how fast the valves were opening/closing at 3 grand on the interstate.

Didn't have one issue.
