Oh and LS7 lifters for a while now have been what GM gives you for a replacement lifter so essentially they are all LS7 lifters now. LS7 lifters will get the job done well. If you have a few extra bucks look at the johnson lifters. You may pick up a small amount of power from them. But overall the LS7 lifter is what is in probably 99%+ of cammed ls motors.

I always figured that 5.3 determined the middle of the pack stages, so a stage 3 on a 5.3 is like a stage 4 on a 4.8 and a stage 2 on a 6.0

awesome. Thanks for the help. Can you think of anything else? I was going to toss a melling high volume pump in it for good measure while I was there.

If you don't do anything at least get better valve springs.

Like posted more camshaft... that stall converter opens the door for a cam up to the low/middle 230's duration. Speed Engineering makes both the 1-3/4" and 1-7/8" headers for that swap. The larger 1-7/8" are only $30 more than the smaller set and will deliver more bottom end and top end torque/power. Replace the cam's retainer plate, oil pump and pickup o-ring. While the engine is on the stand, you're pulling the pump anyways, I'd replace the timing set with a good quality billet set like the Rollmaster (CS1180). When you see the slop in the old chain compared to the slop in a new OEM replacement you'll wish you would have went with a better setup lol.

Those speed engineering headers are pretty decent then? Got any recommendations for mounts?

How much does the truck weigh? What gears are in it? What are you going to use it for?

That stuff is WAY more important to picking a cam, than the brand of the bolts.

3500 roughly, 3.08 gears, rowdy daily driver.

You can drive a truck with **** gears, can’t drive one without a drivetrain 🤷‍♂️

3.08s are going to pose a SERIOUS limitation to the available rowdiness.

I'd suggest something in the mid 220s like some of the other suggestions, TSP Stage 4 Truck for example, but GET SOME GEARS immediately. I'm gonna guess this is the old truck 12-bolt? If so, not the most robust thing ever built, but should be adequate to the task at hand.
