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)

Trying things in the 408 in the Malibu just to see what ET it’s worth

Got some good work in now that the weather is cooperating. Cam, timing gear and pump all in along with ICT Billets supplied rear timing cover and the cam sensor block off doohickey as I’m running this Gen3 block as a Gen4. Found some residual carnage from the old block. I was reusing the Cam retainer plate because it was near new. On assembly I noticed stress cracks and that the plate was bowed. The detonation at the back of the block was hard enough to kick the cam forward and break the plate. Yikes. 😳 Way over paid for a Felpro one from the local store to keep things rolling along.

Got rained in, today. Wanted to get the block mounted to the stand, but I need to do it outside because the hoist doesn’t fit in my garage. So instead I masked and painted the new short block on the floor. Wanted to do Pontiac silver-blue, but all I had left was silver… so sticking with the aluminum block look. But, just as I was cleaning up I found a ICT Billet adapter laying around. It’s the first part of the long block!
