2.66 low gear vs close ratio

I was just talking about gear splits on Moparts the other day in regards to my D100. I would like to have a closer ratio trans in the truck, it's an NP435 behind an over-cammed, stock long-block 400 with 3.23 rear gears. It's about the worst combo you could come up with (I didn't)

In regards to the trans, there is a 50% ratio drop between each gear. The cam starts working at higher rpms so there is very little torque down low. It can be tricky to keep the truck in the power band in traffic when you have to shift. You're either revving the piss out of it or it falls flat on it's face in the next gear. Drives me nuts.

To the OP, whatever 'pass car' trans you have with whatever 1st gear ratio is in it, stay with it and be happy you don't have a gearbox designed for a farm tractor like me. :burnout:

I went over to Wallace Racing to get a better idea of why I was hating my truck. The numbers speak for themselves. Click here for the calculator.
