I don't have all the specs in front of me but he called it an 850ish that will flow like 970-980. Price wise I think was somewhere in the $1575 range but I got the last body in on special pricing for 1450. Complete carb built to spec and comes setup "close" but also comes with full set of jets and bleeds to tune for anywhere. Pretty good deal for a billet carb, tuning and kit.
