not at all. I sent the crank, piston and rod to a friend. He balanced it and sent it back. I put it back in the engine and ran it at superior this past weekend. It was extreemly fast, it pulled harder than a MAX and never reached above 220. I was in my trailer and a few guys came by to ask what I was running because they were running modded engines and the other guy was running the MAX and they couldn't believe how fast it was. I took it out of my car to clean it and showed them what I had done. I sat it on the work bench and said that if anybody wanted the engine, they could have it for $100.00 because I only did it for an experiment. Needless to say, I don't have it anymore.
My budy the machinist said that it wasn't that far out of ballance, he lightened the rod and trimmed the piston on one side then made a couple "divits" on the crank lobe. If I can get ahold of the guy that has the engine now, I will have him take some pics and email them to me.
