need cam advice from 351 guys

[Shaggy]

Sorry to take so long to jump back in so late... those specs look almost exactly like a cam i was running about 10 years ago only real difference wwas mine was 110 centers. That cam should pull real hard to 6 and beyond if you have the heads intake and exhaust fot it. It is a rough cam tto use on the street but i liked it but I am not most people(I also run a spool on the street in my daily driver) I personally like "high" lift cams on the ported stockers... If it was a customers car i would have gone with a little less duration though. My personall opionon on lift for a 351 is if it ain't at least .500 then it is still a "mild" cam.. I know that will stir all kinds of crap up so let me say my reasons before everbody starts to go off on that last statement.

Ok a good set of ported stockers will flow to about .600 before steadying out or even loseing a little, with that in mind even if the port job onm your heads isn't that good at it only flows good to about .500 or even say a real extreme example .400 okay well if yyour peak flow is at .400 then you want the valve to be at .400 as long as possible correct? Welll if you buy a cam tha has .400 lift then the valve only see s that area around .400 once per revolution now if you say get a cam that has .500 lift on the same motor then the valve will see the .400 are once as it opens and once as it closes so twice during a revolution. remember if you peak is at .400 then what you are going to probaly really going to have for best best flow on average (not peak) will be say .350 to .450 with the .400 cam your valve would ever really see any of the good flow above .400...... Kinda like a torque/HP curve and the reason most combinations run faster if you actually shify a little after there peak HP.
