My freind went this route, he bought a cheap F body LT1 2 bolt to build his 383, we installed the ARP bottom stuff and it's holding together just fine. Frankly I don't think the F body guys worry about it eaither even with spray.

ARP Studs are the shiznit...
But that strength didn't exist years ago...
oh, and NASCAR still uses 4-bolt mains... if not cross bolted mains.

Hey, I run a 427 in my circle boat, 12.5:1 compression, av gas, and turn 6800 with her. She's a two bolt and she's in her 8th year, so don't throw the two bolts away. Now she is line bored, decked and she's balanced that is what keeps her together and I never jump on her cold...gosh that sounds a little funny?

Looks like a little more was going on there than just a cap failure. Looks like what ever else was going on trashed the caps and at that point 4 bolts wouldn't mean a hill of beans.
Look, every freakin journal is scored to hell and back.
