The engine was originally built about 8 years ago and was in a roadster. It has TRW pistons, hastings rings, an RV cam, had been balanced, and has had some head work. It was pulled from the roadster and sat for a few years before I bought it and put it in the '52 Chev. That was about 3 years ago. It broke when I was pulling my house trailer. It developed a loud rapping niose coming from #6 cylinder. Grounding the #6 plug lead caused the rap to almost disappear. The builder says that because of the cracked skirt, the piston was rocking on the power stroke and causing the rap. He couldn't tell me what caused the problem. I think that the motor was driven very hard in the roadster, and it might have been weak when I got it. Pulling the trailer put more strain on a weak part and it failed.
He charges 45.00 to do the sonic test. I'll know by Tuesday.
He has got a line on some hypereutectic pistons out of California that are 80 thou over. Don't know the make right now. If the block checks out, I may go this route.
What do you think?
