Re: Comp valve springs 987-16 vs 26918
All of what you've said is true.
As it turns out, there's a comprehensive test comparison (between these two exact springs) done by David Vizard and Comp Cams.
The Beehive is the hands down winner. Valve control is extended by several hundred rpm and this is in an range that has resonable applications. In a cam with .544 lift the conventional spring became unstable at 5500 rpm and a final crash at 5700. The Beehive doesn't lose control until 6750 rpm.
While I do have a set of 26918's, they're installed in my Vortecs and I'd like to keep them complete. Looks like that won't be the case.
