I’m going to run the Cam and housing from my 68spare engine since both the cam and cam housing uses the same on for 68-69. That cam is in beautiful shape and the one that was on the car was the incorrect 67 cam anyhow. I wonder what the difference was?
What do you guys do to tension the timing belt, shop manual shows a tool that looks like a variation on a Burrows gauge, the factory timing specification for the one barrel engine was 0° advance, but this car seem to like 9 to 12° in terms of getting the best possible idle and vacuum levels. However, with three cylinders at such low compression levels, it would make sense that it would absorb more timing to better burn the fuel that was not being sufficiently compressed.
We did have a good look at the head and the valve job looks beautiful. Nothing seems to be mechanically wrong, but will do it careful of the valve geometry once we reassemble the engine after machine work in the block.
