Picked up about 30 CFM from .350 up and 40 from ~.650, not using it all up though.
12:1 414 with a 255/263 @ .050 Solid Flat Tappet .606/.608 lift (1.6's) 109 centers in at 105. Ported 340 Victor, worked 830 Holley annular.
Should go low 13's in my little 2700 pound 4.56 gear Rocky....easy
....maybe upside down and backwards
Seriously though, I had the car over at Lennys and he commented that the thing has a good bit of Natural hook in it, I'm putting a 10" T/A in front of a standard gear 904 so the stall shouldn't be more than maybe 3800 or so, so it won't be real violent off the line.
