    Default opinions on cam selection

    I decided to stroke my 454 and I am looking at a good cam selection. Here is my setup.

    Generation 4 bbc 2 bolt main non siamese
    bored .070 using kieth Black Hyperutechtic pistons
    4.250 crank
    Compression ratio 9:1
    Heads are 049 oval port cast iron 2.19 intake 1.88 exhaust stainless steel valves

    What I'm looking for is a cam with a rough idle. The boat will basically be used for recreational purposes, but I want it to compete on the water when racing other boats on the lake.
    I looking into the Comp Thumpr #11-602-4 cam and was wondering if anybody runs this cam and if would be what I'm looking for in my application

    Thumpr Hydraulic Flat Tappet Cam
    Adv/Dur: 295/313
    RPM Range: 2300 to 6200
    Intake/Exhaust Lift: .522/.507

    The boat is a 1976 sanger bubble deck two seater.

    I know everyone has there cam choices, but seriously call Engle Cams.
    They turn out quality, not just a shelf piece. Ask for Doug the owner, or Chris they are more than happy to spec a cam for you.
    They have a lot of grinds to work form, and can set you up with the correct springs, and lifters too.

    By the way, no one here can call out a cam for you without knowing your exhaust set up.

    Have a friend here on the lake that has the same motor, heads, etc.. you mentioned. He is running a hyd. roller off shelf from Doug Herbert.. .600's+ lift. His heavy layup Hondo runner runs hi 90's on GPS. Combo has been reliable for 3 years of punishment. I can get his exact cam spec if you are interested.

    Running on Empty,
    Everyone is going to push the roller issue, it's the best way to go no doubt, if you can come up with the $$ it's worth doing.

    But if you need to go flat tappet I would at least stick with a solid lifter,
    more HP and it's the same cost, just a valve adjustment here and there depending how often you run the boat.

    Solid lifter cam: Engle part #2225 HL 25-26
    This cam runs hard, definitely has the idle your asking for, I have used this cam in a few boats close to your set up, always a winner.

    If your set on a hydraulic flat tappet cam then go with this: Engle part #2225H same cam in a hydraulic profile.

    To see the cam specs: Choose Chevrolet BB on the pull down menu.

    I would definately go solid roller on a BBC. Lifter bores arent always 100% on the money and a roller takes care if that issue...
