I got knock at just 3 psi with 8 degrees base timing…

On the one hand probably good to know, on the other hand kinda sad because I was having fun driving it and it’ll make it slower to pull tim ...

If so, please let me know. I too am ...

Did some engines, I guess US/California engines, come with an air pump that injected air into the exhaust ports?

Searching this board results in several threads around this subject, and how to get ...

Remember that the 76-77 actually have no rubber at all, the rear axle is solidly mounted to the chassis. They early cars did get complains about road noise when they were released, but its not that ba ...
