I’ve been reading, doing research and have a lead on a good running 2001 5.3L. It’s from a personal friend and I know he maintains his vehicles well.
It’s going into a 1980 K20 my kid and I are building. The truck is lifted 8” with 37’s. Aside from that the truck is completely stock. The main reason for the swap, is the motor is tired. I plan to keep my SM465/NP205 and have the “starter” list of parts/materials to order. Before I put the motor in, I would like to put a cam in it. From what I’m reading, it’s a pretty quick and relatively cost effective way to gain HP/Torque.

Question;

What cam would you go with for best power gains, and still keep reliability. We hunt a lot and are in pretty ****** spots, for periods of time where the truck would be idling. Is there a better setup for that, or would one setup build heat faster that another?

Thank you in advance...

I ordered a stage 2 truck cam for my LS. Haven't driven it yet though.

Stage two cam is a good choice. Installed one in my wife’s Yukon. Performs great.

I put a btr stage 3 truck cam in my truck, it’s probably little to aggressive for what your looking for, I’m running 33’s with 4:11 gears and the sm465 but been really reliable
