4.8L cam replacement 99 Silverado New body style
99 Silverado, 4.8L, manual trans, 4x4, ext cab, lifted with 37" tires.
I'm looking for a cam that will give me more torque for towing and not killing the MPG anymore. I'd like to keep the stock valve train. I'm not looking for max performance gains but a little more useable power. On occasion I move a 30ft camper for a buddy and that POS is heavy. I know I need a bigger truck.
Only mods are cold air intake, FAST programmer, and true duals with cats only.
I've read a bunch of forums and no one mentions a manual truck and all are conflicting on what to use.
Hopefully someone has some first hand experience with them

As the old saying goes, There really is no replacement for displacement. Esspecially when it comes to torque.
The 212/218 low lift 265 cam from CompCams seems to be a fairly popular choice for the mild side. It's just about as big as you can go before loosing on the low end.
No loss in low end torque and you gain in the mid to upper RPM range.
Not sure what gears you have but with 37's but I am guessing you need something like 4.88 to get it back to stock.
37 and 4x4 certainly aren't helping your MPG any.
If you just want a mild towing Cam then have some one spec one specifically for your needs.
