If it dont run at least low 13's I am gonna be really dissapointed!!! My 8000 lb diesel pickup runs 13.8 and it is only 410 rear wheel horse. This truck is over 500 horsepower, and weighs 3000 lbs less. I dont think there is any reason why it shouldnt run with my old lightning! But anyway, if it dont, it will be time to put her up from 7 psi to about 15... It should go then!!! It does have plenty of bottom end, 4340 steel crank, eagle rods, trw blower pistons... etc. And turns out cam size is a .598 lift.
