292/508 question

To your original question as to "Who" ground the cam...........why does it matter?? The 108 version will have a ruffer idle than the 112, and as already stated, there are lots of cam grinders putting out mean sounding idle cams.........personally I think that's a poor way to choose a cam, just my opinion.
The 108 has a pretty raunchy idle at 11.3Scr (with aluminum heads), allrightee. But another thing I liked about it was the little dust-devils my twin 3" turndowns made while idling along on gravel roads.
But the thing I liked most was the sound of those twin cannons at 7000rpm, mixed with the howling 325s, the roaring TQ, and barely being able to shift the A833 fast enough.
