shimming distributor
when new engine was built the engine builder in stalled the distributor and installed shims under the distributor where it goes through the intake. is that for gear mesh(and howe do you know it is the right amount of spacers) or someone else said it is to align an oil hole somewhere in the distributor shaft and you need to open up one of the three little threaded plugs in the back of block to look in and install the correct amount of shims for alighment. im confused and feel stupid asking this question. could someone please help me on this one. i have another new engine and i am installing the distributor and dont know if i have to do something with the shims. i feel like the gorilla with a calculus book and dont know what to do with it thanks art
