Edelbrock carb adjustment

FYI.. I had one of these 260 + cams last cam.. I didn't think 119 miles an hour in a quarter mile was too bad for a Edelbrock and a carter performance paired together... One that came with the car on its 318 and one that was given to me as scrap metal... Neither one gave me absolutely any problem for all the years I had them. I sold them for $150 each and hope they continue to work as they did for me...
I believe your 4 speed masked some of the low speed transition problems of the Carter.
