O.K., maybe I missed a previous post or something,but why so much lift? Is this just an exercise to find out how much is possible?



is this an allout max horsepower headsup type engine?

IMO opening the valve that far past the useable range of the intake port is a waste of energy, reduces durability, increases wear on the valve train. not worth the extra 2-5hp that you might get. springs will have a very short life.
