Well your giving up at least .4 in the 60 foot at least and that is just there. any improvment in the 60 foot is usually X 2 in the quarter. so if you go 1.65 short times 1.87 - 1.65 = .22 X 2 = .44
1.65's would still be poor for your car by the way.
so a 4000 stall, 38 deg total, bring up the shift points, work on rthe cooling a set of caltracs and mono springs good slicks and 11.5's with no problems
Probably more as you work it all out1
