Offset key
|
Who is a supplier of offset woodruff keys for a cam? I'd like a 4 or 5 degree offset but Summit only has 2. Who would be a good shop to build an adjustable Cam gear? |

What engine are you working on? Not trying to be "smart", however couldn't you move it a tooth and use the 2 degree offset to go back or forward to get what you want? |

I'm working on a IH 407. I want to move about 4 degrees one tooth equals 12 degrees according to my manual. |

So the set you have for the 301 works just the same in a 407 and the degrees and everything match up?? |

Dumb Question
|
Dumb question: stock timing is 105* centerline on a 407 right? So moving it up to 98* or whatever, what does that do in the engine?
Can someone explain it? Opens the valves earlier in the cycle but how does that effect performance. Just trying to learn. Thanks. |

Piston then has more time to compress the air that theoretically would produce more heat. Great for performance in a short period of time, but I wouldn't want to run a farm tractor all day in the field like that. |

Get a overer size KEY file it down yourself whoever ground your cam can tell you how much the off set needs to be if you cant figure it out |
