So I have a 2003 LM7 I am rebuilding for my 1995 GMC K2500. Im wondering if there is a list (I have looked and not found one in one place) for good upgrades when rebuilding. Here is what I have so far by hunting and getting bits here and there. Now keep in mind I am not building a powerhouse, I am looking for a slight bump but mostly a super reliable engine for a daily driver.

Outer than the obvious things when rebuilding (bearings, oil pump, new lifter keepers, seals, etc...)

*Upgrade replacement parts for the LM7 engine*
- LS2 timing chain
- Bronze rocker bushing trunion upgrade (to loose the needle bearings)
- Oil pickup tube hold down (for both bolts)
- Four corner steam vents
- Mild cam upgrade w/new valve springs (like the Texas speed low lift truck cam kit)
- 4.8L flat top pistons (to bump a little compression, moves it from 9.5 to about 10.3)
- Timing chain guide bracket and guide (to stabilize the timing chain between shifts)
- LS7 lifters
- Custom tune

This is what I have gathered as UPGRADES for a mild stockish build (again, not really looking for lots of performance). Keep in mind I am am working with a non-VVT engine, if someone is running a VVT engine there is more stuff, I know. I dont wanna build another engine for this truck for a very long time, if at all. I know the trunion bushing upgrade is not really needed for mild performance, but its not that much more than the replacement bearings so its kinda worth it. This is for the engine only, not the exhaust, or transmission, or anything else. Does anyone have any advice on things to add or change?

I hope to build a "Master list" of sorts for the builders out there that want a good reliable engine for a stock car/truck or engine swap car/truck to reference in one place. I know most builds are different depending on desires, but there should be a baseline. "If your going to spend the money, you should at least do this..." kinda thing. I am trying to stay away from aftermarket parts (like aluminum roller rockers) so it can stay budget friendly, anyone can just throw a ton of money at something to make it happen, but not everyone can afford that. Let me know what you all think....

P.S. I can supply the part numbers of what I am using if anyone is interested (I might add those later anyway)
