Does anyone have any specs or have the degrees to tune them in? I've search the net but I havent found any solid answer. I will get it dyno but in the mean time something to work with. Thanks |

It's gonna depend on more than just the cam selection. What is your set-up and what fuel are you using? |

Decking your head will also effect where they need to be. I suggest indexing them in then changing them a degree at a time seeing what kind of effects it has on the dyno. |

My apologies, I assumed you meant how many degrees of advanced ignition timing you should be running with BC 280s, not what your static timing should be. |

Would anyone know if soild lifters are worth the swap over stock lifters for 280 cams? I've already got a new set but I've been reading bout changing to soild lifters for high revs though i'm planning to rev it to say 8.5k MAX if it does |

Solid lifters are really only needed for 10k rpm. I had a set and decided I didn't need them, went with a set of new revised lifters. My limiter is set to 8.5k, never had a problem. It's more of a valve spring problem, you do need aftermarket springs/retainers if you want to constantly rev to 8.5 or above. |
