You may knock off another 3-4 tenths when you get a dominator and victor intake. Way to go!!

i have a 4150 victor in my garage that not ported, the good thing is they can be converted to a 4500 if needed. i think i still have room to grow with the 1000cfm cuz i'm only using about 940 of it according to a engine dyno in WA.

i'm hoping to gain 3-4 tenths just going to the automatic where i don't have to let off the gas and restab it for every single shift.
