I know I should upgrade to the 110 lb Schneider springs but just wondering if that is absolutely necessary on a motor that will likely never see north of 5500 rpm. Am I correct in presuming that there will no be no issues at idle or mid-range rpm?

I ran the Schneider 270 cams with VG33 outers and VG30 inners. About a 15% increase in spring strength.

I had no problem taking it up to 6700-7000 rpm.

So, you will be fine. But to argue, its only $100 to upgrade.

One of those "might as well". Ya know?

Thanks.....Yeah, I know.......just feeling pretty unmotivated these days to do any work at all, especially when it isn't absolutely necessary

I have ben running stock valve springs with Schneider regrinds for years.
