I was under the impression the 64 max wedge blocks were stamped MP for maximum performance.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Thanks Scott.That paint does look original...so would MAR=marine? I read that max wedge,marine & industrial engine where all built in the same facility,is the correct? The 2R through me ... Which leads me to ask"could this have ended up as a max wedge engine "if the builder had picked it when grabbing a block from the storage area? Also could it be a warranty block with the WT ?

How would you diagnose which way it turns(head scratch )
If it turns opposite direction could the crank still be used?

I had a reverse rotation/marine 440 ages ago (sent it to Melbourne to sell actually) and the reverse ones have the hashing on the rear main seal area going the other direction to a "normal" crank. So it would tend to push the oil outwards probably if used the 'wrong way' ?

And now your ebay example. This example is NOT typical of an original Max Wedge stamping. It has the small font stamping as was used in regular production (as correct on a Street Wedge). That said, it does have what appears to be original broach marks in the cast iron and does not appear to have been re stamped. The sideways "I"s are not unusual, I've seen them used in place of dashes or "1"s before, from the factory, so I wouldn't call BS on those. Street Wedges were stamped V 42. V stood for 1964, 42 was for 426 cid (no "6" was used for 1964 engines) and had HP (but not MP). Notice how your ebay example has the EXACT same date as my original example and is just ONE engine before it in build sequence? Does that seem odd to you? It does me! What I would question is; Did someone add some markings to a Street Wedge block to make it appear to be a Max Wedge? Possible, but if they did, they did a great job. The other possibility is that it was built as a replacement or something and was built using different stamping tools to I.D. it than normal production versions. Also to be questioned is the casting date which is pretty early for a 1964 engine. Tough call from just the pics (I'd rather see it in person) I'd be highly skeptical of this one.
