Re: 5-speed "deep thoughts..."

With that tall 3.08 gear, and in 5th gear, your little 250 just isn't producing enough torque to accelerate. You would be better off with a 3.73 rear gear. All too many guys think they need a tall rear gear in addition to a OD trans. That combo typically doesn't work out. You need to have your engine to be in it's powerband at your typical cruise speed. It is also more efficient there.

could you bolt on an OD to a th350? if so how'd that work with 4:10 gears?

Sure you can. Google "Gear Vendors" I never said it would be cheap. It's a .8 overdrive, so with 4.10's....you'd have a 3.28 gear.
