Currently the only thing on the truck is the K&N cold air intakeWelcome,
Any mods currently on your truck? Superchargers are good choice, but personally i'd rather keep it naturally aspirated and work on the internals like cam/heads/pistons ect... If you still want more power, a supercharger is always still available...
Other option is to pick up a GM performance crate motor for almost the same price as the supercharger...
My truck has just rolled over 70k. It is a 5.3. If i do the boring it outhow much will that be running? I have given it a thought.How many miles on your truck? You don't want to add a supercharger to a engine with high miles. Also what motor do you have?

I'm like HotRod, I like head work and cams. If you have a 4.8 or 5.3 you can bore and stroke them to a 6.3 (383).
Im just not sure that doing that will give me what im looking for. Im just thinking if i wanna spend that kind of money i should go with the supercharger, more bang for my buck i believe.Can't tell you a price for boring the block. Find a machine shop that has experiance with the new LS type engine blocks and they should be able to give you a price. Your 5.3 has a 96mm bore, you can bore it to 99mm and it would be a 5.7. Add a 4" stroker crank with the 99mm bore and you have a 6.3 (383). Add some larger valves, pocket porting,gasket port match the intake and exhaust ports, mild cam and you have a nice dependable engine with good torque for daily driving.
