I often visit a crankshaft shop that builds all types of high performance
engines and modifies parts.
You'd be surprised how many engine blocks, rods, cranks, heads I see
there that have been literally polished. When I say polished I mean a
jewelry quality polish job.
Many people have their rods lightened and heat treated before polishing.
I've see wrist pins that are taper cut interior for lightening. You just
wouldn't believe some of the modifications some people undertake on their
engines.
I look at some of the parts and think "Overkill" but everybody has a guru
telling them the latest trick to get into the winners circle.
