I've seen valve float on the dyno. Looks pretty much like what you descibe
Dayle.
Pulls well until it hits a magic number, then all hell breaks loose.
Easy to check. Pull a couple valve springs and check them...if you are a place
with a chassis dyno, there should be a valve spring checker near by.
Back to back with a new set found about 40 lb difference.
Also, beware that I've found Isky has quit selling the good spring sets for the
Spits. We are trying to find a suitable alternative, but haven't come up with
anything yet.
