2000 GMC 1500 Sierra 4x4 build

I was hoping some of you guys could give me some insight into rebuilding my truck. I have a 2000 Sierra 4x4 with a stock 5.3 and 195K miles on it, and the only upgrade right now is a Banks exhaust. I have put a 6 inch lift and I bought it with a 3 inch body lift. The truck has a set of 35 inch tires. I was looking to rebuild the stock 5.3 and give it a few upgrades, nothing crazy just something that can pull my boat and my horse trailer. Should I ditch the 5.3 and go with a 6.0? What kind of upgrades should I look at (heads, cam, intake, programmer)?

If you got the money get a 6.0 and 80e swap, but it will set you back at least 2k to do. You will get amazing results and reliability though. If you are on a budget give Nelson Performance a call and get a custom tune first thing first. Other budget mods are a corvette servo, Ebay CAI, and Cal speed LT's. In your case maybe the best mid range mod would be to swap out your G80 and get a valuetrac and some gears to make up for those tires. I like 4.56's for tires that tall and 4.10's is the very very shortest I would go. Goodluck and have fun.

Thanks for the insight, I'm going to have to do some research to figure out what some of that stuff is. This is my first build so I'm kinda new at this.

i have 4.10s in a 2000 scsb 5.3 on 35s , it does good, but 4.56 would be better especially if you were to go bigger than 35s. 75mph at 2100rpm with 4.10s
