efi-diy,
That 292 did have a problem, when pulling it apart, it was noticed that the alum gear on the camshaft was coming off. This could have had a severe impact on cam timing.
It did run perfect on the dyno, not quite 500 runs, but a bunch. The only failure during the dyno pulls was the cam bearings.
It is running happily today in a mid 60's pickup. The gentleman loves it. He pulls trailers and uses it for fun. It is a driver.
