Grind's #294 and #101 do not require addition
modifications to the valve train making them quite popular. I chose grind #294 to retain a smooth idle.
But I have heard of some incidences where the 101's did not effect the idle on our superchargers.

My pal Stephen Gunter at Gunter Automotive has the
following DYNO sheets for the two popular WebCam's.
This Dyno sheet for the grind #101 was recoreded on a 4A-GE.
It shows a 6.6 horsepower gain at 7,200 rpm with gains recorded only above 5,900 rpms.
apprx. While this Dyno sheet for the grind #294 was recorded on a
4A-GZE, it shows an 8.8 horsepower gain where it powers down at 5,400 rpm. Clearly, had the
dyno of this #294 been recorded all the way to 7,500 rpms, then a gain of 15 horsepower might have been
observed. And maybe the #101's show a greater performance increase on a 4A-GZE too. I have been
told many a times that the #101's were a much more powerful cams then the dyno sheet suggests.
