What is the determining factor if you need (want) 1.5 or 1.6 ratio rockers? Thanks, C-dog |

Mr. Zilla, I am seriously looking at the roller tip rockers the Cox bros. have. I am not sure which ratio, or does it make a differnce? |

Those rockers are good for a drag race motor, but I had a set I tried to run on the street and they did not oil the valve stems enough.

Yes, no oil to the valve tips is trouble.I put a spray bar into my valvecover to keep the roller tips oiled on my race engine. http://www.dutra.org/pictures/engine/pa ... -oiler.jpg Truth is that the factory rocker arms are good for most performance Slants so spend your money somewhere else. DD |

Doc, Thanks for the sage advice on the rollers, I will take it. That valve cover brings back bad memories of Y-block F**ds, if you ever had one ya know what I mean, overhead oilers or no oil, it didn't matter they were better off fried. C-dog |

I blueprinted about 3 sets of stock rockers, and found that the ratio varied from 1:1.45 to 1:1.57. That means that for a little time you can find a matched set of any ratio you want. Just use a pair of dial gauges and to measure both ends as they rotate on a spare shaft. It doesn't have to be fancy, just stable as you measure. |

I have drilled & tapped the boss at the end of the main oil galley, I run a hardline up from there. I have also used brass "T" fittlings at the oil pump, where the sending unit goes. Again I run a hardline up to the valvecover and screw the sender into the other leg of the fitting. DD |
