    Default Need help choosing a cam for my 460...

    I am doing an intake swap on my 460 and figured now would be a good time to do a cam swap. I want a cam to have a lopey idle and have good vacuum....What does everyone recommend? I have an edelbrock performer rpm intake and edelbrock carb on it right now.Also,its a 20' Southwind with a berkley jet

    ive come across a lunati cam...here are the specs
    idle-5000- duration at .50" 207/213 Lift int. .503/.535

    or a crane cam
    1500-4500 duration at.50" 204/216 lift int. .487/.518

    All and any info will be greatly appreciated,
    Jon

    i'd shoot for alil more duration to help the heads breathe, exhaust ports are horrible on those heads you're not gonna get away with much more lift, but you should be able to pull off 530, and make sure you upgrade springs

    Dare to be different, if it turns out great you can claim you planned it that way.

    I run a Comp 280H with .530 lift, and 230 deg @.050. No problems with logs and reversion, but I'm not comfortable with more duration than that. You may need to machine the spring seats for this lift.

    You can get away with a little more duration but OEM Ford heads like a alot of split. I would look for something like 215 on the intake and 230 on the exhaust at .050". Make it around 540 lift on intake and 500 on exhaust.

    Jon,

    Don't know enough about your engine combo, but if the longblok is essentially stock then the Summit Cam p/n SUM-3501 will work for you. 0.503"/0.503" - 218*/228*@0.050 - 114 LSA. Close to what Straub recommended and with the "good vacuum" you desire.

    Next power ugrade: ditch the Edelbrock carb for a Holley 850 cfm Double-Pumper.

    Did you upgrade your valvetrain or need anything else besides the cam to finish the swap?

    I got a complete cam kit when i built this motor 5 years ago. I would get a cam kit and go from there. I only have roller tip rockers on mine.

    Get the cam kit, you will be money ahead, and yes you need to have the heads (spring height and pressure) set up for the cam.
