Just following on from another post...........how many of you guys are jetting you're motors wayyy out of whack from what holley supply out the box?

Example...i had to drop 8 jet sizes on a domie 1050 back & front to get this motor to run clean (plug chop), this is a 605 cubic inch , maybe there's a pattern to all of this.........

99's front 99's rear, still looks a little lean. seems to like as much fuel as I can give it! O2 sensor will tell me better next time out.
