Well, it turns out the great deal on the engine wasn't so great after all. While checking it out, I found an exhaust valve leaking bad when I pressurized the cylinder. It looks burnt or almost there. I dropped the heads off at the machinist yesterday for a valve job. And a lobe on the cam was wiped. Soooo, the engine now sits in a pile and there goes the budget. Fortunately the pistons and cylinders look pretty good with almost no wear apparent, so I should be able to get away with a quick hone, rings, bearings, cam lifters....
Fortunately, SBC stuff is cheap!
