Max bore size on 340 Resto Block

cool, never saw this before with both lifter angles in the block casting…..any Chance there is another one where this came from? ;-) is it a 4 bolt on the middle mains?

Well when i saw it i had an X block in the garage.
So i would not buy it before he had lower the price 2 times.
I doubt i will ever find a block like this once more in Sweden .
And yes it is a 4 bolt main caps ;-)
