WEB Cams, #101 and #294 Grinds


Web offers two different cam grinds for the 4AGE that I have tried, the #294 grind and the #101 grind. I didn't "degree" either of the cams, so these results are based on "drop in" cams, thus eliminating the expensive adjustable cam gears. The specs are as follows:

Results:
In my dyno testing of these two cam grinds I found NO DIFFERENCE in power from the #101 grind over the #294 grind with STOCK INJECTORS. The idle on the #294 was smoother although both worked fine for the street. I installed larger injectors after my last dyno session and definitely had better power, although I will never have the opportunity to dyno it.

Opinions:
Both of these cams offer a less expensive alternative to the expensive HKS cams, but there were a few downsides...

Ignition Timing: I noticed on the #294 grind that I was unable to get the distributor timing where I wanted it. No amount of installing/re-installing the distributor on different teeth would make it work. On one tooth I had max timing of 10 deg BTDC, and on the other tooth it was minimum timing 18 deg BTDC. Since stock timing of 10 deg BTDC was best on the dyno, this was OK but still annoying. Note that I DID NOT degree these cams, so that may have helped the situation.

Wear: On the #294s which were cut from new billets, I had virtually no wear. On the #101s which I had stock cams hardwelded and re-cut (to eliminate the above timing problem) I noticed some wear at the extreme tips of the lobes after 5000 miles. The wear wasn't excessive, but it was noticeable. Web has a 1 year replacement warranty that I may exercise my right to use.


Recommendations:
Based on my experience, the #294 is a great drop in cam. It has a significantly better power curve than stock cams, yet still idles well and is totally streetable without injector modifications.

If you want more high end power, the #101 will probably provide that with the help of more fuel. As I said earlier, I didn't see a difference with the #101s until I added fuel. The pull on the cam was perhaps a few rpm higher than the #294, but both slammed into the rev limiter rather easily.
