found this summit cam below was put in by PO in my '68 383 (4bb 600CFM, 67 primary/73 sec., doublepumper, edelbrock performer intake, cast iron exhaust, 3.23 gears) and I am wondering (with my limited engine knowledge/experience) if detail suggests any significant performance improvement over the stock cam? any comments much appreciated.
