Jim,Was any post failure autopsy performed by the builder, to identify the exact cause of the problem? I know if I built it, and it failed in that time period, I would certainly want to see it again, to see if I could recitify the problem, and work with you to make you happy.. I am sure Mike is the same way.
We took what was left and inspected with Mike. He was the first to open it up. There was much discussion in the past on this, and the bottom line determined nothing conclusive other than bearing seize/failure. Nothing bad on Mike or quality of workmanship implied here. He did offer to take care of me as you would as well. I decided to throw in the towel until something better comes along. Distance being the factor on AM&P, I've stayed with Opel Engineering in Streamwood Illinois. Otherwise, I'd would with no hesitation use Mike and AM&P again.
I understand your questions regarding fuel system etc. My entire combo and chassis was well overbuilt for the motor. That being said, when I went with the BBC I changed absolutely nothing with exception to a BOP tranny adapter plate and other basic swap mods. I've been very pleased having more time to race then wrench with two (reasonably) troublefree seasons.
Since then I've also improved my chassis to 8:50 certification and someday hope to put an aftermarket BBB combo back in.
What I'd like to see is something a little bit more conclusive on this thread. Like many others, it still seems circular with a ton of expert opinion. On the other hand -- maybe that's the best there is considering the circumstances and numerous flaws associated with pushing the limits on 32-38 year old blocks.
