Really made a difference
Had to file a little bit of each side on the 10 Degree bushing due to product variation in either the bushing or distributor plate. More than likely the distributor plate. Nonetheless - the bushing once fine tuned worked great. Engine runs fantastic ! Thanks for making this product..... Before I could not get enough initial advance in my mech distributor to get the engine to run properly without overshooting the mechanical advance ultimately leading to too much advance ALL IN for my engine. This helped solve the problem , I was able to bring in more initial which stabilized engine vacuum and actually picked up 3 inHg at idle once tuned, and also was able to lower the primary throttle blades on my Holley to get the engine back into the idle circuit of the carb. Would recommend to anyone with high lift , and duration cam that is driven on the street and use a standard centrifugal advance distributor.
