I have a Keith Black conrod on my desk. It cost new more than my GFs car. I polished it with a buffing wheel at my mates school (hes a teacher) , and it was a bastard to do and put it back on its piston and leave it around as art. Its Made from some odd unobtanium, and went back to the dull matt collour in about 6 hours... No wonder I had so much trouble getting a shine.
Anyway most of the people here wouldnt know what a KB motor does. Apart from
300 plus in about 4 secs and 5000+ hp for less time...
