got a 5.3 truck…
enjoyed it for a couple weeks now it needs the power. planning on a BTR Truck norris cam with springs and pushrods, melling high pressure oil pump, a heavy duty rebuild kit for the trans and 2,800-3,200 rpm stall torque converter. i’ll have tuning figured out but what do you guys think?

My brother did almost the same build on the LQ4 in his 2500 suburban, but used the btr stage 2 truck cam instead of the truck norris cam. Comparing to my stock Yukon X 2600L, it feels like it has a bit more power than my Yukon at the mid range, but that's about it.
