Comp, Lunati, Mopar?

Many cam blanks are from the same foundry, metallurgy is one thing to consider but would not steer me away from a cam. I would go with someone who has the best support. Comp is very good, have the .904 profile lobes and can custom make you a grind in almost any lift or duration you can ask for and within limits of their blanks. Hughes is very knowledgeable on Mopars, MP is more often a miss than a hit. I spec'd an MP cam on a digital CNC and it was not accurate even between lobes. Lunati has the best lobe designer right now and his cams should work very well too. Might just come do who can get closest to the specs you want.
