re dyno after strange60 i finally got on some rollers after installing the strange60. 4.10 gearing was the same and my exhaust is prolly a little more freed up but i'm very happy that i did not lose much power. it was actually a hotter day too but new #'s are 386.9/372.8. old #'s were 393/377. i've had zero issues with this rear end besides a slight whine at higher speeds and loved that it bolted in soooo well. i hope this will help anyone researching built rear ends.

stock 10 bolt with yukon 4.10's. i know people inquire about hp/tq loss with the addition of a built rear end.

i personally was expecting a lot more loss so thats why i went to the same dyno for comparison. my original #'s was thru a single cut out open and hooker aerochamber. this session, my exhaust is now 2 dynomax 12" bullet mufflers welded in line and dumped before the rear end. it is loud to say the least.

it truely is an impressive peice of equiptment.
that's pretty sweet! when i hit the rollers back to back when my 9" went in i lost 8hp and something like that in Tq. nice thread though, it seems a lot of people **** and moan about losing a few HP from going to a real rearend, when the difference isn't noticable, especially if you go from a stock 3.42 rear end to a built one with a larger numerical gear like a 3.73, 3.89 or 4.10!!
