carb rear and gears. Any idea how much more power i am looking at?

[newlevel98]

Have a zz4 crate engine 3 inch exhaust. In october i am putting in a holley 670cfm street avenger, 3.73 richmond gears and a auburn pro series diff to make my car posi. I ran a 14 with the motor and stock rear, gears and carb. I am guessing low 13s maybe high 12s with my new mods. Anyone agree or disagree? I cant wait to get it done and get it on the dyno.

What kind of trany are you running?? I wonder if 3.73s might be too low for you.
