Default 1970 L-78 Nova Restoration; Saga of The Green Bastard

And Engine Teardown !!
This is one area where the Green Bastard did NOT rear his ugly head.
I know this engine had been gone through at least twice by local speed shops and had seen LOTS of street and Some Drag Strip action so I was not too certain what I might find.

A valve cover load spreader is peeking out from the oil pick-up screen. He was in there with two friends. THREE valve cover load spreaders and a medium handful of orange silicone sealant chunks YIPES ! I still have a hard time believing this thing survived.

Crank and Bearings had some striations but nothing too serious. May have gotten away just polishing but the crank was still standard so I had it ground .010" to be safe.

Pistons were in very good shape with no ridge on the cylinder walls. Was bored .030 with new pistons on the last rebuild. odometer shows about 67,000 (with 4.10 gears, uncorrected speedo) so not a lot of miles... not sure what the mileage was upon rebuild. The Machinist that deglazed the block said it looked pretty fresh still.

Heads going out to machinist for freshening. Resurface the flywheel and give the block a serious wash and deglaze the cylinders for new rings.
