Got all the lower control arm and shock brackets welded on. Next I need to cut into the center section and install the upper control arm mounts

Pulled my 6.0 out of storage to rebuild. Bought this engine as a warranty return from work. Lost oil pressure at 3,345 miles due to a bad oil pump. One main bearing was shot, but the crank journals are good. Everything else is good. It’s an LC8 with 821 square port LS3 heads. It’s from a CNG vehicle so it has fancy inconel exhaust valves and hardened seats.

If I can find an aluminum LC9 then I will sell/trade this. But at least it will be built and worth more money at that point

Had to cut the sides of the housing out to make room for the adjustable upper control arm mounts. I plated them in and welded them all up. Did all the heavy welding with the pumpkin installed to try and keep stuff from warping

Then used some 3d printed jigs to hold the brackets at the right angles and width and got those installed

Just need to get the jig fixture from my buddy to install the 9” ends and she’s finally done

Small update. Lack of energy and motivation since having another round of the Covid

Got the strut tower holes welded up and smoothed with all metal body filler. Finished welding the lower half of the firewall. Dunno if I’ll put any filler on it. Need to trim the pinch weld and work on the upper cowl area next

Lapped the valves in. Vacuum checked the ports to make sure they’re sealed. Then installed the seals/springs/retainers

Reused the exhaust valves - inconel for CNG
New hollow stem LS3 intake valves
BTR spring kit with titanium retainers


I also assembled the BTR rocker trunnion kit. Way faster with an arbor press than the hydraulic shop press

I fucked up and forgot to order rod bearings last week so there’s a little delay. I will gap the rings and replace the cam bearings while I wait

Block painted
Cam bearings installed and checked
Crank polished by willy
Bearing clearances set
Piston rings gapped and assembled

Still waiting on the camshaft. But my dads coming out tomorrow and I’m gonna supervise him learning how to assemble a short block. We’ll see how bad this goes, but at least I’ll have a scapegoat when it blows up
