plugging hole on 327???
I am cleaning up my father in laws '68 C10 with a mild 327. I recently installed an edelbrock intake, carb and valve covers. I recently visited a parts shop because I was having issues with my valve cover breathers and the employee mentioned since I installed valve covers with breathers I will now have to plug a hole in the block behind the distributor.
Is this true? If so can anyone give me some more info as to how and why?
