hughes or comp camshaft

I did a 422 (340 bored .060 over rather than .030) with iron heads I ported. I used the tried and true H-302-2 from Crane. It's a full hydraulic, with similar specs as the Comp XS274S but a little larger at .050. That engine runs pump 89, gets over 17mpg, and runs 108mph in a '72 Challenger with and auto, 2200 convertor, and 3.23s. If you have heads that flow in the 245-255 range at .500, I think either cam will work, but the Hughes is always more money. I'd use the Comp. From the sound of it, it will not run out of steam before you run out of willingness to hold your foot down.
