the 4 bolt mains are actually worse in a drag race engine. the other two bolts remove too much material from the crank webbing. i actually have a 4 bolt block that whole crank fell out the bottom on a nitrous back fire!! now i listen to the old school racers that only want a 2 bolt 400 block!!!

 

My guess is you hit "new message", instead of "reply".

 

yep, i am a moron!! LOL
