I will be re-building a '56 truck 235 with mild cam, dual 216 Rochesters, dual exhaust, etc as a daily driver and since there is not a lot I can do to the exhaust in the way of reasonably priced porting, was hoping I could use a dual profile cam to advantage. A longer open time on the exhaust would seem to be a good thing. Are these cams a reasonable move, and if so, are they available and from whom. Anyone have any experience with these cams on the 235?
