Imo, there must be some fairly substantial limitation in the induction/exhaust system(and possibly combined with lowish CR) for none of those cams to get the motor to make 1hp/ci.
When the local stock car tracks around here went with create engines for 350's they dyno'd a bunch of stockish mopar combo's and had a hard time getting the hp down equal to the Chev's they end up added 150 pounds to the dodgers plus lesser mod's and my cousin could still pull on them out of the turn even when he had to run a smokey stock 318 short block for a few races.
