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.
