I don't understand

I put 42,000 miles on my small block 354 with two different trannies both with .64 OD. Cruise at 1,300 rpms in 5th with no trailer hitch jerk.

4,000 miles on Hodges 408 with 3550 .64 OD. 1,500 rpms in 5th., no problem.

A couple of thousand mile on Lainhart's 1965 KC 427/487 620 hp 3550 .64 OD. You can cruise at 1,800 in 5 th with no jerking.

Coach's KC 428/461 TKO 600 .64 OD 1,800 no jerking.

Coach's Unique with a Pond's KC 482. He bought a TKO 600 with .82 but after a few months bought the parts and swapped out for a .64 OD. Cruises at 2,000 easily.

Now, none of these motor would pull from 1,300 - 2,000 if you stomped the gas pedal to the floor very quickly. But down shift to 3rd or 4 th and you're off like a missile.
All of these motor were build with a lot of low end torque. Easy to cruise at low rpms.

If you want to see videos of these cars cruising at low rpms just email me.
We would laugh at how low I could cruise. Got to be a game on the back road to see how far I could go in 5th.
