366 SPRING

[OLDEARL93]

I WOULD LIKE TO FIND OUT IF THE EXTRA RPM'S ON THE VALVE TRAIN WOULD CAUSE PROBLEMS WITH SPRINGS OR VALVES, HAS ANYONE HAD PROBLEMS

[VEfreak]

I've never heard of anyone ever having a problem with the 366 spring. But when you move up to the 3600 or 4200 rmp springs, that's a different story. You will be safe with the 366 spring.

Won't get you to valve float territory unless you are in the habit of flooring the engine in neutral.

I'm sure that running at 3200 RPM versus 2400 RPM is bound to take longevity out of things, but just because you can run at 3200 RPM doesn't mean that you have to. They might only last 700,000 miles at 3200 RPM as opposed to 1,600,000 miles at 2400 RPM...
