Post your 12 second small block combos

well i havent ran my setup at the track (nor even drove it for that matter) but i thought i might post it...some have told me high 12's are in it, others told me low 13's at very best, so im gonna be optimistic and say it might run high 12's

forged crank 340 .30 10.5:1 cr
stock untouched x heads
comp 280H cam 480 lift, 230 dur. at .50 (single pattern cam)
rpm air gap intake, modified 750hp holley carb
windage tray, deep sump pan, HV oil pump
1-5/8 headers, 3 inch exhaust with borla racing muffs
3.91 gear, 5 speed, 29x12.5 MT sportsman tire (i think this is my limiting factor), stock leafs with one added and clamped, comp 3 way adjustables rear, stock front /6 stuff up front
id say 3500lbs with my skinny as in it (all steel car)

If this car runs a 12.99 i will be the happiest **** alive since the motor is milder than childrens chicken wings

i also think location, track temp, and all those variables play a big deal as well
