I'm wondering if anyone makes a manual gearbox that I can mount inline behind my manual trans in my truck that would give me another higher gear...or overdrive. It seems like this should be a simple thing...just a two speed gear box...push in the clutch and switch from 1:1 to overdrive.
I've looked at Gearvendors...they seem way over complicated and way too expensive for me.
Seams like some of the older larger trucks had something similar to what I'm talking about...I'm hoping to find a wrecking yard item I might be able to make work.
Basically I need better mileage out of my '84 W350 with TBI'd 416 stroker motor. It's got plenty of torque to pull higher gears, but the RPMs are way too high at freeway speeds. I could change both rear-end ratios...but that's spendy too.
Any thoughts?
