Good to know. I've heard arguments on both sides and never knew what to take of that.
I like Sam's view on the blocks.

Did GM use ferritic or ductile iron to cast 4 bolt caps and flywheels .If so is it possible that some blocks were also cast with same iron.Thanks Marc.

I think the blocks and 1st and 5th main caps are the same. High performance blocks and some truck applications after 1968 got nodular 4 bolt maincaps on 2-4 positions, identified by the N cast near the part number. I also had a 1966 L-79 Chevy II and I believe it had nodular 2 bolt caps. Usually these caps came with forged steel tufftrided cranks as well.

2482 caps are nodular iron and as far as I know all of the 400 blocks got nodular iron caps.
