Dang, how much $$ to powder coat brake drumsFinally got my axles back from the powder coater. As always he did a great job. That and alot of smaller stuff. Guy who is rebuilding them cant get to them for 7-10 days as he has about 50 (yes, fifty) motors to build. Last time I was there I counted 38 stands with motors on them....there were plenty more on the floor. Someone has 3 chevy BB's to pick up and he has no room til they do. No hurry for them anyways. Gotta get the drums turned and new u-joints in the drive shafts too. Then the fuel line debacle......guess I'm bending my own.

Zach, those engines rarely have injector failure. You can do the noid test again to verify, but I bet it's mechanical. Pull the valve cover and examine the valve springs on #2 VERY closely as it is not uncommon for them to break. A running compression test may also work. Been working on these late model trucks the last 18 years and spring failure isn't uncommon on high mileage engine. Worst case is a wiped cam lobe. Good luckTuner came back today. Trans acted like it should, he was able to mostly tune it, got it out on the road, about a mile on the Hwy. Came back and said it had a dead miss. Got out the temp gun, sure enough, #2 is dead. That hole was dead 3 weeks ago too, we replaced the injector then after he checked it with a noid light.
Pull it in, let it cool off. Swap #2 and #4 injectors. Doesn’t follow, #4 is still firing perfect. Swap coil packs, doesn’t change. Check the plug, it’s black like it’s had spark, but dry. No fuel.
So I’m gonna redo the noid light test tomorrow. If that checks out, it’s not the harness. At that point I’ll pop off the valve cover to check for bent pushrod/who knows what. If that’s not, compression test I guess. I’m about over this swap.

Shitttt. Didn’t even think about the cam. It’s got new LS6 springs from Michigan Motorsports in it. It did have a bent pushrod when I took it all apart but found nothing else weird and couldn’t pinpoint what caused it. Also don’t remember which cylinder it wasZach, those engines rarely have injector failure. You can do the noid test again to verify, but I bet it's mechanical.

I need one
You should either buy this one or replicate something similar as you have the know how...

Got the bed pulled off... cleaning out some things in the shop and then I’ll pull the bumper, hood, fenders and core support before it gets pushed into the shop. Got everything I need to put the 4” lift on, install the blazer 30 gal tank, new-to-me bed floor, and a bunch of other stuff while I wait for the motor to come back from the machine shop. Guess I should start a build thread at this point..
