Would studded mains be strong enough up the 10 psi of boost? I really don't want the extra cost of splaying or 4-bolt conversion if is not necessary

 

Yeah, it's been hashed over before. A lot of guys say that you will be hard pressed to ever find an engine failure due to the fact that the block was only a 2 bolt, not a 4 bolt. I am doing mine splayed because I want the added security or piece of mind but it is not necessary. A lot of guys build them with 2 bolt and studds with no problems at all. A friend of mine had a 355 LT1 with a Vortech and 10 PSI that was at 574 RWHP and it was only a 2 bolt block, it has lasted. Do a search and you will find many threads on this with a lot of good info.

 

I brought up that question a few weeks ago in the nitrous section. There seemed to quite a few guys well over 600fwhp on nitrous with a studded 2 bolt without any problems.

cool....good to know. That will save me $400-$500 (maybe more)

 

I made the 600 rwhp on a studded 2 bolt with no problems. I am pilling it up on the dyno friday see how much more it takes.

 

I have a studded 2 bolt block as well. No problems for over a year.
