Try this again
h0trod, I was trying to post but my computer kept trying to lock up. Ok, if you've got the 2.97 1st, a 3.42 would likely be a good gear IMHO. 3.42=10.16 in 1st. 3.73=11.08 in first which would be just like my 2.66 w/4.10's.
Now keep in mind what 327NUT said about lugging. If this 450-460hp stroker has a pretty big cam, it ain't gonna be happy in 6th gear at low speeds(its gonna lug the engine). Might not be able to shift to 5th or 6th until you're exceeding the speed limit by alot. The rear gear selection may be a trade off between enough to make the od gears useable at highway speed and not so low as to make first gear like a tractor. Alot of the rear gear selection process also involves how much camshaft is in the engine when it comes to double overdrive transmissions. My big X large camshaft tries to lug the engine at anything under 3000. Food for thought. Nolan
