Decision time - Injectors
Hey guys, Time to order some injectors. Rather than use the ones I had in my prior build, I think I "might" want to just get some new ones. But I have a few questions. My goal is to build a reliable, fun, street motor. It's in a third gen F-Body with a T56. 1. How accurate are most companies out of the box without verifying their stated flow rate? 2. Need help settling on a good brand if I go that route. 3. Are my current injectors (Bosch 280150558) worth reusing after a sonic cleaning and flow-match? Current combo used green top (casting 280150558, rated at 42# - have seen 43.5# on some sites). My build is N/A and anticipated to stay that way for awhile. I will be verifying my prior tune with HP Tuners. Here's my combo: Block - 6.0 iron, bored .030 over (4.030”) Crank shaft- Stock, 3.622” stroke, ground .010” Main bearings - King MB5293MC .010 (Standard bi-metal aluminum silicon with anti-friction coating) Pistons - Mahle PowerPak 4032 forged 4.030" with .945" wrist pins Connecting rods - K1 Technology 012AE29610 forged 4340 H-beam (6.098” with .945” wrist pin) Connecting rod bearings - King CR807SI .010 Oil pump - Melling 10295 with mid-level spring Oil pump barbell - Improved Racing (reusing, with inspection ) Oil pan - Stock 98-02 LS (reusing, with inspection Oil pan baffle - Improved Racing (reusing, with inspection ) Camshaft bearings - King CS5171HPT Camshaft - BTR LS3 Stage 3 v2 (reusing, with inspection) Timing chain - Cloyes Hex-a-Just (reusing, with inspection) Timing chain damper - Trickflow Specialties (reusing, with inspection) Lifter buckets - new GM (reusing, with inspection) Lifters - LS7 (reusing, with inspection) Heads - stock 243 castings Valvesprings - BTR upgraded (reusing, with inspection) Head gaskets - GM 12610046 (4.100" - .051" compressed thickness) Head bolts - reusing ARP (torqued 1 time, reusing with inspection) Pushrods - 7.400" x .080" (reusing, with inspection) Rocker arms - (reusing stock rockers, with inspection)

Few of us drug our rigs out to test and tune this past weekend. Shakedown passes mostly and setting expectations for new combos. Had a good time, learned a little bit, and laughed a lot!
