I would be willing to give it a try, just the guy I talked with from afr suggested the 290 oval port for my use. I like the darts and trick flow as well they just dont flow like afr does. My goal is to hit 600/600 on motor maybe a little more and about 750-780 with the spray. As far as bottom end goes Im looking at scat, lunati or callies. Appreciate the suggestions.
