Re: Overdrive choice?

this is getting complicated. And heavy! To avoid relocating a shift lever the whole drive train is getting relocated!
I would just run the 420 for now and save up for a 5 speed.
planitary overdrives create more drag than a 5th gearcausing loss of milage.
There is no point in having a higher gear if it uses the same amount of fuel to turn it!
