standard two bolt production block (below)
standard production 4 bolt block(below)
splayed bolt 4 bolt main cap block (below)
"The more power you make the more load you put on the crank & ultimately the mains.
The higher the rpm the more load
The longer the stroke the more the load at a given rpm.
The heavier the reciprocating parts the more the load at a given rpm, power level & stroke.
The rotating mass is not important if it is in balance (big if ) in regards to loading the mains.
I don't really care how many bolts are in the block, you can use crazy glue if you can make the surface area enough to handle the load.
It's about how much clamping force you have & the area it is spread over being enough to handle the loads you are going to put on it.
It just happens that 4 bolts over a larger surface area is stronger than 2 bolts of the same clamping force over the same area or in the case of a 350 a smaller surface area .
Crap,,,, I feel like I am repeating my self in different words
