331 stroker camshaft selection

[metman4ever]

Hey guys, need some help in finding a camshaft for a 331 stroker that I am building. I am looking at keeping the the power and torq between idle and 5500. Anyone know of a good cam for this?

My 331 turns on at 1500, pulls to around 6500-7000. Heads are Canfields equivalent to AFR165's, 10.4 to 1 comp ratio, Ford Z303 cam with 1.7 rockers (.585/.585 lift, 228*/228*@.050 Intake is a repop high rise 3x2 with three Holley 250 carbs.

i guess I should have listed what I have. I have gt40 heads and intake, 30# injectors 1.6 rockers and and should be around 9.7:1 compression. thanks for the info baddad457.

Call these guys and tell them what you want,

The GT-40/Explorer type intake is kind of limited to 380HP. What heads you planing on? Lot of cams to choise from, but like posted before, ask one of the cam experts.

Its always best to talk to the pro's about cams..they will want to know weight, gear ratio, tire size, converter, head info, compression ratio, induction info, even header length. OH and what you are going to do with it. Looking at your profile im guessing its not going to be a pro stocker. You are going to have a lot of cylinder compression that you could bleed off with a longer duration cam, but you will lose some bottom end. If you put a mild cam in it you will HAVE to run minimum 100 octane. I used to run a Pontiac with 10.75 cr on the street and it had a mild cam and had to pull all the timing out of it AND use octane booster just to keep it from knocking while daily driving. But reset the timing and throw a couple gals sonoco in the tank and LOOKOUT! If you want instant throttle responce and torque for climbing and crawling dont go too much over a stock cam. If you are going to muddrag race get one like BADDAD457

My 331 is fine with 93 octane Chevron fuel. Initial timing is set at 14* BTDC. Never pings.

Thanks for all the info guys. had anyone upgraded the stock in-tank pump to a higher flow rate in-tank pump?

I'd talk to either Ed Curtis at FTI or Jay Allen at Camshaft Innovations. Probably the two biggest names in SBF custom cams.
