> i was always under the impression that 4 bolts held the main better than 2, but a converted 2 bolt to 4 bolt with splayed caps was the best for strength, even stronger than factory 4 bolt. Atleast thats how it works for 350 blocks from what i’ve seen.

The 400’s bigger main cap (Diameter of 2.65 journal crank compared to 2.45 for a 350) causes the outside bolts on the four bolt blocks to actually weaken the block in the main web area making them more susceptible to cracking under high stress.
