valve spring source for Schrick 276 in NF head?
My engine builder has advised me that the stock NF-code valve springs will
not be happy with the Schrick 276 cam....
Specs are as follows:
available lift before bind: .065"
seat pressure: 60 Lbs
max lift pressure: 175 Lbs
All of these specs are _very marginal_ for race use. The valves and HW are
all light-weight enough, but the cups are rather heavy, could really limit
max RPM before valve float. The available lift before spring bind would
spell reliability problems and premature valve spring failures.
Anyone know of a source for appropriate valve springs?
Thanks,
