Dart Big "M" 396 Sportsman block...

Maurice, I still have one of the blocks to assemble, so I am sure the paperwork is still at the shop. I will look for the machining paperwork Tuesday and get back to you.

Alan, both blocks that I have built, have siamese bores and the same casting # as the 427 Big M block. Also both blocks were around 4.11??? on the bore size. They were both purchased through Atech. I will try to call you later this week when I am at the shop, probably on Tuesday. The first block had blind head bolt holes, but the latest has two on each side that goes into water.
