Most street performance engines will come very close to 100% at peak torque. I know of race engines that getr closer to 115% but these are not low rpm engines.
Thanks moper
How does a "oldschool" cam grind affect the VE compared to a new more modern grind of an camshaft, with a faster ramp and wider LSA.
My guess would be that a modern grind would give a more effective VE?
