My 440+6pk motor made 415 track hp with a single 850DP, stock 906's and a big solid cam, hdrs. If yours is on a par with that corked up and with a good tune, with a weight of 3800 at the line it should run 108>109mph which is normally a lowish 12. However with those tyres you'll prob lose over 1 sec off the hit, I would say mid>high 13's. Some 29" tall slicks would be the way to go for a 5500 trap rpm inc. slip and 12.2's@110.
