just about every year i get some new idiot in like that!(usually a honda/toyota fart pipe owner) just as fast as they come in they go out the door, i have made it a point over the years that if i find some one on the outside talking crap about me my business or my family , no questions asked i just go jack them up !

if i was in your situation i would not pay any attention to him, i am sure that most people already know that he is stroke and expect him to do what he has done with your engine build and his car.

you should get him a large FAIL sticker!
