Default TH400 and 4.56's

So im switching the car from M6 to A3, Ran a best of 10.48 @ 130 with the m6. wondering if i can make it through with a 28" ET Drag, TH400 & 5000 Converter. I know it will drop MPH by switching but it should get faster 60'ft's. just wondering it i can make it through before hittin 7200 rpm

Prob is there, there is converter slip, if it was a perfect world with no slipping loss he could do it, but with that gear, and prob 10% slip he is going to be hitting the limiter at around 118-120

Meaning if he plans on 120-130 trap speeds to put a 3.73-4.10 gear, if 4.10 he would be hitting in the mid 120's
