I have two gear boxes for my Jensen - a four speed and a five speed. I can legally use both, the JH had both boxes in the US with no name change on the car or anything like that. I understand the 240/260/280 changes preclude 240 folks from using the update/backdate rule to run a five speed. Five speeds for the JH appeared in 1975, while the four speeds ran from 73-74.

Both boxes have a 1:1 top gear. The 4 speed is stronger than the 5 speed. 4 speed is a Chrysler small car/truck box, the 5 speed is a Getrag piece that grenades a lot, according to JH folks. 4 speeds are like a&*holes, 5 speeds are like rocking horse sh*$.

My question is this - how do you 240z folks get along with a 4 speed box? Any tracks that pose big problems (I'm in the SE)?

Thanks,
Ron
