idle question
will a cam with a .488/.488 lift and a 292/292 advertised duration produce a choppy idle?

yes, particularly if it is ground on a LDA of 106 or 108 degrees.PLANET EARTH, INSANE ASYLUM FOR THE UNIVERSE.

Just to add to tech's info, the smaller displacement engines will idle rougher. With the little info you gave, if you were to install that cam in a 305, it would be choppy. if you installed in in a 406, you wouldn't notice it nearly as much.Objects in my rear view mirror are a good thing unless,.... they have red and blue lights flashing.

I’m guessing that you are asking me, “why not”?Originally posted by DennyW
Why not ?
If so, it is because the larger cubed engines have a larger air pump, so to speak. For instance, if memory serves me correctly, my 406 has lift in the .650 range and duration @ .050 somewhere around 266 degrees and 272 degrees., yet it idles ok. The 292 cam probably only has duration of 244 degrees. But another factor that comes into play is your compression. The more compression you have, the more duration you can have and still obtain a decent idle. And as Tech said, depends on the LSA.Last edited by TyphoonZR; 01-17-2006 at 10:50 PM.

Actually, that cam on a 350 will be a radical idle. Depending on the compression, good luck with your brakes.Objects in my rear view mirror are a good thing unless,.... they have red and blue lights flashing.
