I am rebuilding my 228 GMC and am planning on installing a more agressive cam. I have some reading and it suggests stiffer valve springs to prevent float. I was thinking of a cam with a 3/4 grind so that the duration is a bit longer and was wondering if this aggressive enough to warrant stiffer springs or will my stock spings do, proided they haven't sufferred fatigue?
Thanks,
Elias

I used stock springs many years ago when I put in some wild cams and never had valves hang open, but I would certainly use new springs whether stock or stiffer. | | |
