    Mines real close to that build.
    Same exact cam.

    I have Brodix 280cc runner square port heads, TR with 660's, but a little less compression than yours.

    Turns an A to 5800. (625 HP) Was a JC, but put a JG bowl with droop and place.

    my experience with that program is they are very "generous" with their HP
    figures I look at that program as a CC "sales tool" some are close, others are a little far fetched-

    Cstaub might be able to give you a harder number. But I would think 575-600 would be a more honest guesstimate.

    well if you want to see somthing funny, punch in your same specs in the
    compcams "camseller" program, but drop your compression ratio about 2
    points, and then look at the HP, now tell me it's believeable of course
    I forgot you CAN make that kind of power, but ONLY if it's a stock surburban short block

    Yeah, I kind of wondered about the XM 286 thing myself. Comp Cams part numbers usually coincide with the advertised duration of the cam.
