I'll take a guess...#3 rod broke?
3 was broke along with a grenaded case in the motor when I bought this car last summer. That engine had 3 laps on it, the owners were pissed at the engine builder (I'm not mentiong names) and gave me a whore house deal on the coupe with bad motor ($2800). I just had to run over to Chicago to get it. Yesterday when I was giving Hank Scott grief on the phone, I brought up this engine builder and what I have been running across after tearing down the motors he has built. Chrome rings in the second groove, upside down rings, smeared oil rings (when an oil ring lower ring slips out of groove as the cylinder is installed) 1mm rings filed down to fit in worn out std cylinders that have just been rehoned, that kind of stuff. Almost like the builder of topic had a kid throwing top ends together for him. The engine in my coupe pictured above was a back up motor from when I ran sealed engines. The engine was purchased from John Case. Cam case ran it the last season of his asphalt reign in Legends Cars. It smoked like crazy at an idle and we could not keep a hed in tact on it. It kept lunching heads. I decided to whip the top end off of it after installing another good head, retaining the bad smoking habbit. We found standard bore with filed 1mm rings in it. I had it bored and new pistons installed. Little mix-up lead to this scenario.
It's going to be a long season !
