Loose HP?.... That's a new one.....I will let all the Top sportsman, Top dragsters, promods, and all the other bazzillion racers that run 9" diffs know that.
Lets agree to dis-agree, bottom line, I'd rather put less cash in a 9" then a 8 3/4....did my time with those, and they did serve me well.
But pound for pound (pun intended) I got more bang for my buck, and I feel warm, fuzzy and secure, everytime I let go of the button.
I do admire your effort to try different things with the 8 3/4, and that billet carrier is really gorgeous.
