    Buy a built s&s 124 or 116. Been there got the Tshirt. Problem with a build like this is you end up with weak HD cases and a massive engine. Cases are not designed to handle that big engine

    Plus you loose it when you sell it



    Quality engine. Put s&s IST ignition gives two year warranty stronger cases specifically made to take the big inch power


    Or.

    Buy HD 124. Out if box 135 hp/tq

    Bolt in ride have fun. If you sell bike bolt stock engine back in move new engine to new bike

    I was just on Black Widows site and I was looking at the BW-62 grind, pretty similar to the that Reaper 594 with more lift. With both the Reaper cam and the BW, would you consider them to have an aggressive ramp rate? Black Widows site stated the same that the 117" are very responsive. :cool:

    A lot of compression on the static side, but the corrected factor drops me down to 9.8, can live with that.

    the fueling 594 is in a class of its own split lift split duration a hell of a lot of duration on the exhaust side . compared to the other two cams and a lsa of 114.and the intake close @ 56 deg abdc its a runner but it also likes gearing. you meant the crane was similar to the bw

    Would you use an HD crank or not?

    $1500 for a DH 4.375 crank is not a bad price and it is already trued and plugged vs. the SE crank that would have to have all of that done. If used an SE crank then you would have about $2k-$2500 in it..

    When I was looking at Wood's site, I was looking at the Prowler corrected push rod geometry support plates. I didn't look at the price, but in an engine like a 117", is that geometry that crucial?

    I ran a 124 in stock HD B cases as SNS doesn't make B cases or didn't at the time
    wish I had the picture of the bore to the cases to fit the cyl, you could see the side of
    the center case bolt and it was v shaped as it is bored with the cases making it a weak spot, going over 107 in HD 103 cases (96) means you have to bore the cases.

    this is where you get the weakness and the main bearings have to be replaced
    with better stronger bearings and support plates.

    By the time you add it up you are not far off from a 120R out of the box
    that is made to be a 120R from HD SE.

    As to flywheels, SNS they were designed to be 124 flywheels

    Nothing wrong with building it, but if I do it again I'll just buy a
    new HD 120R and bolt it in, much less labor involved as well
    as the work required to build your own, you could go from 103 or 110
    to 124 in an afternoon of wrenching.

    that center upper case bolt area is very thin after case bore work is done . My buddys softail only has room for a 1/4 24 bolt in that area when his was done only hd cases were being used also

    :gah::gah::gah::gah::gah::witsend: I think JB needs to start a shop that customizes bikes and that way he gets paid and he spends their money to produce a nice bike!!! JB thinking out loud gets very dangerous!!! I just need a cocktail, take a deep breath, and try and quiet the voices in his head. :roflmao::picked:

    No, I am not planning on building anything this year. My goal is to get you on a different bike. Just curious how people would go about building an engine from the ground up. We could just buy one that is already done, sure, but that just doesn't sound like much fun to me. I would rather be the one that has control over how the engine performs. Of course with a 117 CI engine, it is made for only thing really, no matter how it's built. Relax, just going to get this one running top notch for now. :D
