Fleming if you ever find a solid main web that’s the day Paul tester and Andy miller will be friends again and the world will implode

Well here's an update. The block has 395558 "2" on it. The driver's side cylinder head has an "8" on the front corner. It has the 10 bolt valve covers with the "Oldsmobile" script stamped on them. The original paint is gold which tells me it's pre '75. It has HEI, but that may have been retro-fitted.

How much you want for the valve covers?

Some January & later '74 engines across GM had HEI.

Gonna be pretty hard to part with those 🙂

So, a 68-70 350. Allegedly, a "high nickel" block. I don't buy into that theory, but it's a good foundation, nonetheless. Get an offset ground 330 crank, SBC rods, flexplate/flywheel, and light pistons, bend over, and kiss your *ss "Good bye" with a 7000rpm screamer!
