Bought another Hemi 4 speed listed as a 833

You are lucky in that you have a denser population base, so far as used parts. N end if Idaho, bleeding over into MT and WA, things are sparse, and there are MANY of the "I know what I got" (and overpriced) mentality. Around here you are more likely to find an over priced box advertised as a 4 speed, and it turns out to be a worn out aluminum case OD box, out of a Van or pickup.

My favorite things to make fun of are old clapped out motorhomes for sale, that "you can sell the parts and make money." Hell I'd need 20 acres to do all that. One guy around here on CL had a motorhome torn down for at least FOUR YEARS on there trying to sell stuff. And since some are 440's of COURSE they are "gold"
