Warming up my 5.3
So I have an 89 short bed regular cab gmc truck with a TBI 350 and 700r4.
Engine has unknown miles, odometer stopped working at 156000, I'm guessing she's north of 200k by this point.
After some debating between a 454 or an ls the ls won the debate and away we go.
I bought a junk yard 5.3 out of a 2001 suburban, took her apart and loaded everything up and took to the machine shop.
Met a guy on Craigslist who's charging me 300 bucks to rework my harness and flash the computer.
Machine shop quoted me 1200 bucks for the work, ouch that hurts. Told them let's do it.
Fast forward 5 days and I'm ordering parts from summit, and brain tooley racing.
Ordered ls7 lifters, gm performance valve springs, brian tooley stage 4 truck cam, brain was out of stock for pushrods and timing set so off to summit I go.
Call in order a set of flst top 4.8 pressed rod pistons for the rebuild, shopping for pushrods and the guy says hey, do you know we have a brand spanking new 5.3 block, finish machined on sale for 299 dollars? What I say heck yeah throw her on a truck and send her to tulsa.
Just dropped my machine shop bill to 400 or less, not to shabby. Brand new block and 500 bucks less than machining the old one.
So I'll have my crank polished, rods checked and new pistons pressed on, valve job for the 862 heads once I choose an oil pump, buy rings, bearings and gaskets we should be ready to put her together.
Sorry for the wall of text.
Hoping to resale my junkyard block for 150 bucks or so to offset some of the credit card splurge if not I'll keep it for a spare.

So should I go ahead and plan on buying bigger injectors? I don't know what the stock ones can handle. Also what about the stock throttle body? Should it be upgraded? I was trying to maintain a 3000 dollar budget but that's looking less and less likely
