Needing some advice. I just purchased a new 350 sm. block for my 65 Impala. I'm using the old 3 quarter cam from the other engine rather then a stock cam and considering going back to stock since the engine is idling high.(1500rpm) What are the pros vs cons of the upgrade? This will be a daily driver.
