I have as Phaff 555" in my 28 eagleand am looking to replace the cam. The cam currently in the engine is different from the cam phaff put in it. I have a feeling that the current cam is hindering the performance. The engine is a std deck gm bow tie with a dart single plane intake manifold, dart aluminum heads and a 1050 dominator carb. I'm looking for a cam to replace the present one with that is more appropriate for the engine. Unfortunately I do not have the grind specs on the present cam but the dyno sheets I have from phaff show the engine make 680 hp at 500hp. I know this is probably a long shot but I'm looking for any help I can get.
