Which means using more spring than Comp recommends since their rpm ranges are MUCH lower than reality.
Set up an XFI cam per Comp's recommendations in a 350/355 and you WILL have valve train longevity issues. A stroker will bring the rpm range down nearer Comp's incorrect listed ranges so it wont be as pronounced there.
