Food for thought: I purchased a different Summit brand distributor for my 351 Windsor based engine. The distributor was beyond the warranty period by the time I fired the engine. The roll pin sheared within about 50 miles, possibly due to the custom nature of my
oil pump, cam, etc. I submitted a poor review of the distributor. Summit offered lots of words, but nothing of actual value to get me to change my review. I didn't. They removed my review. ... My point is that you may be seeing only selected reviews of your product on Summit's web site.
