a friend of mine has a 350 with an edelbrock torker II series cam with 292/300 advertised duration, the thing is his idle is not as rough as i thought it would be with that duration i thought the bigger the duration the more rough your idle will be, i dont know if im right, 292/300 advertised duration should be enough to give a rough idle, does lift play a role in idle roughness please help me out thanks a lot

Duration and overlap play the biggest role in idle quality. Lift is not a factor. Maybe he has his timing advanced to smooth it out a little.

yeah steves right. a cam with a a wide lsa and minimal overlap will idle much tamer and actually quieter than the right cam will. if you are good with a sawzall and an arc welder you can cut between each exaust and intake lobe and re-weld the seam once the desired overlap is achieved. the only drawback is you will have to repaint your cam bearings, rotate the lugs, and run synthetic washer fluid for the first 100 miles after service. OR you could replace the cam. i KNOW what i'd do, i didnt buy this welder just to fix computers and vcr's all day! good luck.

A smaller displacement engine will have a 'rougher' idle than a larger one with the same size cam.

If all you want is a 'rough' idle though, I've got a blown power valve and a couple bad spark plug wires for sale

Just an example of the same:

My 362ci Windsor has a 298/292 Intake/Exhaust advertised duration, but idles perfect at 1000rpm and only has a slight lope at 750rpm.

The trick to mine is that it's only 224/228 Intake and Exhaust at 0.050" lift, and it was rotated to a 114 degree intake centerline.

The cam was ground to give me an idle that I could use with a stock stall speed automatic and enough overlap to run 11:1 compression with 92 octane fuel and proper timing.

advertised duration numbers are like hairy buttholes. duration at .050 helps keep the numbers straight and comparable.
