questions on timing an engine

The only right way to do this is either obtain a performance distributor, or modify the one you have.

If you can braze or gas weld you can do this. I'll look if you are interested, somewhere there is a chart that relates the advance weight slot length to no of degrees mechanical. Then just buy a "spring kit" and get to work. You may have to tear the dist. down a few times, but I'll guarantee you that when you are done, you will KNOW how to time an engine, and how to drop the dist. in "right the first time."

A "cheap" fix is to open the dist. and pull the heavy spring OFF. Then "power time" the engine for 35* or so at high RPM.
