productive morning. Lunch break. Going to attempt to finalize the exhaust, install plugs and wires, carburetor. Then it's driveline measuring time, then if I still have energy I'll start the fuel system.
When we yanked this engine, I flipped it and pulled the pan and a couple main caps. The bearings were decently worn, but not bad. This told me that the engine had run. No metal or debris was found, good signs. It had been sitting for several years at least, and had a good coating of Chevy sludge. The carb was dirty, so I rebuilt it. I was obviously not the first person to open this Q-jet either. If the van was running with that carb in that condition (springs missing, metering rods out of place, wild idle adjustments) it couldn't have been running that well. I'm pretty confident in my Q-jet rebuilding abilities though so at least for the initial rundown it'll be good. The cap and rotor look to be in very good shape, and everything seems well with the distributor. I'm assuming the lack of metal in the bottom means that the cam still has all it's lobes. And no sludge. I'm pretty confident it's gonna run well.
I did not clean the valley, this engine has been rebuilt, we put a mic on one of the piston skirts, and it appeared to be .030 over, which means our 400 is actually a 406. Which is neat. But I know the rebuild was ok since the mains show so much wear. At least I'm hoping the bearings were replaced. Anyway. One more, then back at it.
