That was not much help, guess you just needed to say something. It has a 1600-stall and can't make any power, was thinking 2200. Anyone have any real info to share??
Actually, that was the best sdvice you'll get but the term "factory converter" is little ambiguous...the stock factory 340 converter is an 11" high-stall and should stall at 2250-2450 behind a stock 340.
Yeah, the 600-700 RPM increase in stall will probably get about 50-75ft/lbs deeper into the powerband, which should help "launch". I don't agree with swapping in deep gears and killing overall driveability for an occasional better launch. 3.55's would be nice, but I don't think worth the cost unless I was buying a gear anyways. And all this is baised on a 28" tire - taller tires would require more gear.

A 28" tall tire will be small on this rig even though some called for 195/75s. A 235/75 is roughly 29.4" tall depending on maker but I have that object my 5th ave. I agree a gear swap to 4.10s is a lil ridiculous for a driver but why need a hard launch in a 4wd? He11 put it in 4low and call it good 3.5grs would be good for all around. My 89 2wd shortbox with a 318/727 will break loose the 31x10.50s it had in the rear(peg leg) and our 2wd Rc wouldn't. 89 has 3.5s and the Rc had 3.23s both rabid 31s in the rear
