408 rwhp dyno

My best 60 ft is 1.90, I don't rev it to the moon and dump it. I load it a little roll out and hammer it, second gear it will spin some. I am running m/t drag radials, on the car always.. Every tenth in the 60 is 2 tenths in the quarter, I know I have some work to do! Will try and post dyno w/ cam card. Wanted to add that my ignition system consists of a mopar perf. electronic ignition with no msd and 8.5 mm wires. Anyone know if it's worth it to upgrade, I have a new msd pro billet e-curve, am alittle afraid of messing with it.
