Makes my want to try the MP 557 cam some day. Do the old MP grinds make less valve train racket than the newer more aggressive profiles?
i had a 557 in my scamp for a while. the clatter was UNBELIEVABLE. it didn't matter how tight i ran it. i put a 509 in, and the car is way lopier, quieter, and faster.
for what is the good life if not doing things thoughtfully?
