with a stock motor t-body to oil pan, pullies, msd digital6+, K&N,3.73, cat back, and flow tech shorty unequal length headers, a 125 shot (wet). I went 13.1 @ 107 with a very trac. limited 60ft.
That is mph enough for a 12, and you have better heads than I did at that time. There should not be too much of a problem with that goal.
