Reply to "2 or four bolts main caps, is it so impotant?"

4vandproudMember

the extra bolts don't add a whole lot, if a motor is going to float the 2 bolt mains there isn't much 'window' until the 4 bolt mains start to dance around

a 2 bolt block with the fastener holes chamfered to prevent pulling material up and lifting the main caps off the block will hold more power than a 4 bolt block not prepped with chamfers. the outer bolt holes also remove material from the already sketchy bulkheads

guys get the line bore done but how many actually check the flatness of the block registers? after a couple rebuilds the registers can be out of wank, that's where stability begins, the area right around the bolt holes
