We have one in shop right now and have looked it over and checked it for brinnel test and it seems to be a very soft block as it tested in the low 140's
To give you an idea a 010 block is around 180ish and SHP block tested mid 190's and the Little-M and Big-M are mid 230's because of the nickel content.
It lools like the block is finished honed and I have not probed it out for locations for deck heights, cylinder bore loctaions, lifter bore locations ETC.
Looks like once the cylinders were honed they decked the blocka nd left a burr at the top of the cylinder as there is a zero chamfer on the tops of the cylinders.
The lifter bores have a huge ridge at the top and on the bottom of the bores I would assume from machining the soft cast iron.
With that soft of bore it would wear the cylinders out in a short time as well as the lifter bores.
The rear main cap is not even flat where the pump sets on and they have welded what it looks like a insert where the threads are.
I will post pics later on and what we find for demensions in another thead.
For right now it does not look like a very high end peice and is surely a copy cat of the Dart Little-M block
I beleive PBM is selling them with their name on them!!
