8" 5400 stall. 4.30 gear. The Dyno it is going on is the same one my 511 went on. When I showed Dwayne the sheet from that I believe he thought it was about 20 HP higher than the #'s he'd see on his. So maybe it will go 640-650?
I thought the 511 if it nosed over 700 it would just do it. It made 743.
I like to guess low then I'm not bumbed out if it don't make that.
