Since my 60 fts are slow by .03 to .04 for my et, i agree there may be good cause to go to the 4.30 from 4.56. The data logger shows the launch rpm at exactly 6,000 rpm at launch/full stahl, and i have another converter that i believe to be about 400 rpm tighter. Shift point showed exactly 7350 rpm. The explanation of methanol torque versus gas tells me an alky combo will like a tighter converter?
I have some more shock testing to do also as the ladder bars are only 30 inch long and it looks like the Big Gun afcos may not be valved stiff enough.
