i run the 278mm 3000-3200 in my 2012 5.3 rcsb. i ran a 13.79 in the quarter with stock cam last year. i ran a 13.61 with dod/vvt comp cam last friday nite. you wont notice a loss in top end either. id be more worried about breaking a driveshaft at top speed!

 

Funny you say that lol... Mine snapped a month ago, have a high speed balanced two piece setup now ... My girlfriend actually blew it up which is the ironic part

 

Any info on the 2800 stall. just curious on how it is doing with the stock cam and dd.

 

Nothing yet... Should not this weekend but the next for sure.. Had some stuff come up but I'll keep you guys updated

 

Put it in today.... Pedal feels Like stock but I feel like I'm burning has truck runs up to 27-2800 rpm gets moving.. When at about 30mph stab no more tire spin at all... Going get retune Friday evening... Truck feels like I'm slipping clutch till I'm out 2nd and just cruising

 

get a couple videos to help us visualize. Your description doesn't exactly sound right... Light throttle should be tighter than that.

Any suggestions?? Perry sure a retune will correct hopefully
