    Getting a cam kit from Northern.
    Are either of these cams decent for mostly street use?

    Speed Pro 1500-4000 RPM # CS1014R 278/288 adv duration .420/.443 lift + $36.19

    Speed Pro 2000-4500 RPM # CS1013R 214/224 adv duration .443/.465 lift + $36.19

    you need to make sure your lifters can support the lift of the cam also. Other than that they both sound good, what else do you do with your truck. what kind of wheeling?

    Lifters come with the cams. Valve springs are new but stock. Anyone know what lift they can take?
    I use the truck as my daily driver and to get down mild to moderate trails for hunting and fishing.
    The truck has to pass emissions, but neither of those seemed too agressive to make it fail.

    If the cam lift is to big for your valves they will not work.
    Did you call nothern and ask them about a cam choice?

    pasted them from the website. The reason I'm asking is I'm buying a cam and rering kit for a 350. I want to get a little more out of it than the stock cam and still get by emissions
    I had wondered about the numbers too. I thought low lift, longer duration was for higher rpm's

    The duration for the second one is @ .050 lift, I'd like to see both of those no's

    Stock newer valve springs should handle these fine....

    I'm leaning towards No 1 in the selections....

    OK, that second one is suposed to be 288/298 adv duration.
    Anyone running these numbers (for the first cam) with a stock 350 as a daily driver?

    .050 on the first are 204/214
    Had to look some of this up in the catalog. The website doesn't have a whole lot of info.
