Guys,
I'm going with a forged 383, LE2 heads, and a D1 with the SDCE tensioner. Since the motor is apart I'm contemplating whetheror not to spend the extra $500 on a 4 bolt splayed main cap conversion. I talked to the engine builder and he said if it was his car that he would just go with ARP main studs and that the caps were overkill unless I was planning on making more than 650 rwhp.

What do you guys think? I don't know if I plan on going with n20 or maybe upgrade to a F1 blower in the future.

Go ahead and do it now. Much more expensive to go back into the motor, if you happen to decide that you want to make more power. Looks like you're already considering that anyway.

 

Do it now. Even if it MAY not help, and it could be an overkill, think about how it would be to go and have to do it all over again if you didn't.

 

20 years ago I made well over 600 hp on a plain old 2-bolt 454 out of a station wagon, shifting at 7500; thus proving that good block prep goes a long way.

Having said that, it will NEVER be cheaper to do the conversion than it will be right now, so why not buck up?

 

definately do it!

 

Well, $500 now or another $5k later when a cap walks.
