Big argument going on. Does a 1981 vette have 2 or 4 bolt main bearings ??????????

Colvin's book, "Corvette by the Numbers", page 109 states that Flint records reflect that 1981-1982 Corvettes received only 2-bolt applications. This is for block # 14010207. Also indicated is the remote possibility that a #14010209 block from Tonawanda might have found its way into a 1980-1982 Corvette.

As there were no engine choices in '81; the L81 was the only choice, and it was only rated at 190 or 195 hp....why would anyone think it was a 4 bolt main engine?

Anyways the block in my '81 is only a 2 bolt.

I know my 81 has a 4 bolt main. Oh, maybe because we installed a brand new ZZ383 Vortec. Anyway, I have not even removed the pan on the original.
