My carb is back together. The carb shop only charged me $28 for the rebushing job, much to my surprise. I ended up using the brand new #60 jet I bought from my local speed shop. Everything works great. The engine idles smooth, power is smooth, and while I don't have tons of power at WOT, it feels like the engine is doing all it can with a 1 bbl, rather than choking from an overlean mixture. I even managed to break the tires loose briefly on wet pavement.
A big box of parts from RockAuto has arrived, I will be doing an HEI conversion (using an LX-301) shortly, as well as a new timing set. I plan to swap to the NGK long nosed plugs when I do the HEI conversion. Engine mounts need to be replaced, and my rear springs are pretty much shot. I have my work cut out for me, but the newly rebuilt carb has helped out tremendously.
Thanks to all who posted. I appreciate your help!
