408 hyd roller, too much spring pressure?

Sounds good,
I also just got info from Lunati. They say 138/369 is just fine, and that the cam can handle up to 500 lbs. He didn't think there would be any problems with the stock lifters either.

Well, I guess I'll stop worrying and keep running! At least as long as no new noises appear.

They said their cast iron roller cam can take 500 open pressure? As long as they knew you weren't talking about a billet core, sweet.
Just an echo.. as far as I know ..it's the constant extreme seat load that can hurt a cast iron roller cam and not really so much the open of your average load requirement. Rock on!
