im getting ready to drop ina cam for my 07 nnbs 5.3 right now i have CAI,Wheatley tune,Headers , the best time i got was a 13.9@99

what size cam and stall would it take me to get AT LEAST a 12.9xx


and before someone says it cant be done , be quiet cause its possible i've seen it done ..

would a 220/220-581/581-114 do the trick or would i need to go bigger ?

I think a comp 222/224 with a 3600 stall would get you on your way. It just depends on how streetable you wanna keep it

*if* it was me - TR220 (proven) and Circle D 2c-3c stall...that will get you solidly into the 12s

220 cam and 3400+ converter, you'll have 12's easily.

so a 220/220-581/581 114+4 will do it ....

valve events occur 4* advance center.

it shifts your powerband down. 114 LSA - 4 = 110 Intake center line. If it was 0 degrees advanced it would be 114 ICL.

According to Stock48 every stock ls timing chain he's seen has 2-3 degrees of slack (retard) in it.
