Hi guys I picked up a 2011 silverado I'm going to be swapping the 300k mile 4.8 with a low milage gen 4 5.3 while I'm swapping everything over I want to put a small cam and delete vvt and dod I'm fine with doing springs, pushrods ect because I'll already be in there this build will be on a STOCK STALL I already own a max effort NA step side with a 4200 I understand the difference it can make but this truck will be towing the step side and various other work truck tasks I don't feel the want or need for a stall

 

How much weight and how often will you be towing? Hilly mountains or mostly flat? What gear ratio in the rear? What's your planned WOT shift point?

 

212/218 in some flavor

 

Stage 1 btr truck cam.

 

I'll be towing about once a month the step side and trailer together should be right about 8000 so it's a little heavy for the truck but it will be all flat so I don't think it's a problem it has 373s in the rear and I was planning on keeping it low around 6200

 

Then I suggest a 6.0 with a 212/218 in some flavor

 

yeah I started thinking about going ly6 but i already have the 5.3 i think itll be fine im not trying to pull anything crazy and im not concerned about performance if the 4.8 didn't have so many miles I'd send it and haul with the 4.8

 

For the 5.3L do either the BTR Truck Torque 202/202 111+1 or the Summit SUM-8727R1 200/205 113+4. Both will pull great starting in the low end, should peak around 5700/5800rpm, and keep pulling a hair past 6k.
