Some questions for you knowledgeable folks

[Recon6]

I'm fully aware this has probably been asked a billion times but im not good with the internet at all and not sure how to search for it.  

 

I've got a 14 silverado  I'm very mechanically inclined and recently started coming up with money mainly due to kids getting out so im starting to add to my truck.  Next up engine.  What are some cheap upgrades for power for these l83's.  Yes I know I'll be doing a cam swap soon but I'm speaking as to things like vacuum pump delete to remove static power loss from engine, manifold swaps things of that nature.  I read somewhere people are deleting the vac pump and pulling vacuum from the manifold or maybe it was from the TB for the brake booster.  So basically I'm inquiring about little things that can be done that don't cost a whole lot.  I've never really dove into these gen v engines.  I'm more into old school SBC's.  Is their interchangeability between say the late 90's LT engines to these gen V LT engines?  I've got the L83 and just trying to figure out little things I can do.

answering these questions over and over again starts to make one feel crazy, lol  there is a search bar top right corner.

 

personally i would leave this truck alone and buy a nice old 80's square body you can tinker on.

I agree. I bought my 14 GMC near retirement with the purpose of modifying it with a super charger. I've been driving my 92 Chevy truck that is modified I was going to replace with the 14. I was driving my toys a few years and hadn’t kept up with the new truck evolution good or bad. Driving my new truck to the exhaust shop I noticed a V-4 display on the dashboard and had a WTF moment. The exhaust made it more noticeable. Sh$T! I hit the net an joined this website and got educated. Kept my 92 later sold the 14. Five years later bought my Avalanche. Buy an older vehicle make it your own. You get tired of it or break it it won’t cost as much.

after messing around with my daily truck and learning to tune this technological nightmare, i honestly I would have had more fun building and tuning a SBC, doing heads cam, rebuild the trans and carb tuning, maybe even low boosting.

 

these trucks need lots of upgrades, and i can spend $10-20,000 doing it correctly, where-as an old 80-90's car or truck could be completed for $5-8000 and have more tech support. Aftermarket race parts evolved with those old SBC. the new LS/LT aftermarket is either junk or Exotic stuff $$

 

look around California craigslist for beaters to build on

here's a nice example

There is going to be no noticeable power gain with removing the vacuum pump, leave it alone.

 

Run E85 if available. Get the truck tuned.

 

Past that it's going to be bolt on parts to get more power.
