It was a new 300 with the 6.1 Hemi so it really shouldn`t take much to get 13.3`s out of it.
My old enigne combo went 13.3`s-13.5`s with everything else the same so I should easliy get get back down there at least.Traction is my biggest problem as I lowered my launch rpm to 2000 and still spun hard thru first.New engine is 9.5-1 340,Comp cam,ported 915`s, 2.02 intake valves,LD340 intake,4 spd with 3.91`s.I also dropped some wieght by removing the 4 spd console and swithcing to a fiberglass hood and front bumper but the track scales weren`t open.
