    Default bbf cam help

    Would this cam be alright with some head work and stock bottom end. Or is it too much? Can get for free and brand new!! Attempting a rebuild for first time. 460 .030over Thanks johnf.

    Its going to be lazy on the bottom, that cam will make peak power at 6k if installed straight up and good flowing heads, It has 4 degrees of advance built into it, If your determined to make it work (Trust me I understand free parts) I would install straight up or as far advance as possible(with in reason) to get some of the bottom end out. If the heads are stock it will put a nail in the coffin, peak power on a set of as cast DV3 would be right at 4500 and wag of 420hp/500tq Vs say a set of edebrocks RPMs that would be [email protected] If your running wet headers be mindful of reversion sucking in water

    Also a FYI, say you stick with a basically stock heads and If I'm right at my complete guess of 420, you would spin a A impeller 4900. However if you have a heavily ported or aftermarket heads and hit closer to 550 your going to be around 5350 (with a A) and out out of the efficiency of the engine. A B cut would be a closer match at 5650
    Keep in mind this all hypothetical what if stuff.

    Not knowing much about what your application is other than what has been given...

    I'd throw it on the shelf for the next build that involves more compression, different intake, smaller impeller, etc...

    So, I wouldn't run it this go around... and if your running logs... not just no, but hell no.

    That is not a good cam for what you described...... pass and use something else.

    IMHO

    I assume you don't have adjustable rockers? So you would be stuck with a hydraulic lifter?

    *** considering this is your first rebuild......***

    IF your on a TIGHT budget and have adjustable valve train set up go with the smallest solid lifter (flat tappet) cam you can get... Watch your break in VERY VERY VERY VERY VERY VERY close and use a good high zinc break in oil... my 2 cents... Clay your set up for valve to piston clearance...

    I saw someone mention D3VE heads which are 97+ cc if my memory is right so you want FLAT TOPS, no inverted dome... PLEASE contact D.S.S. racing in St Charles Illinois to see if they have their BBF pistons ready to ship yet: Forged Piston | Stroker Kits | Crate Engines Great pistons and they make their own forgings in the same building that they machine/finish/ship from... I couldn't believe my own eyes when I saw that last month ( I was there to spec out an order)...

    Not sure where that leaves you with regard to reversion...

    Comp Cams used to have a .605 lift 294 duration standard part number available...

    Just my 2 cents...

    ALSO have your block decked for .002 in the hole, I think your deck height should have the piston about .010 down in the hole at present time... For a bump in compression...
