Dear
Customers,
2001 has started out well for us. We had a healthy sales increase over 2000 and we’re still very busy. Harriett and I enjoyed our trip to Florida and Clarence, Chuck, and Shannon took care of everyone quite well. I spent a lot of time designing new cam profiles and I’m excited about the results.
Don’t miss a chance to try out our newest hydraulic profiles in your mild street engines. These cams have extremely short seat timing, which promotes higher cylinder pressure, better throttle response, more torque and better fuel economy. We have all the masters and can produce them now.
Check the comparison between our 202H280 and the Isky 256 Supercam. This is a good example of why you can’t compare advertised duration figures if you don’t know where they are checked.
While our cam will perform better, (see reasons why above) the Isky will have a rougher idle which some people desire even at the expense of some performance and economy.

These cams should not be used in higher compression engines unless they
are ground with closer lobe separation and the intake centerline retarded
slightly. Max cranking compression should be under 200 lbs.
There
will be some new flat tappet designs added as well. They will primarily be in
the 240 to 250 degree ranges. Instead of the 28-degree major intensity found in
our very successful XTL series these cams will have a 26 degree major intensity.
This is accomplished by employing a revolutionary new intake ramp and using our
already track proven XTL closing ramp. These cams will require a slightly
tighter lash and are not intended for very high rpm. Lash maintenance is more
critical and valve spring quality will be more important. Although these
profiles have considerably more lift, the nose radius is still conservative for
good wear characteristics. The following profiles are planned.
| SXTL Profiles | .020 dur. | .050 dur. | Cam lift | 1.5 lift | 1.6 lift |

Future
design
We will have some new roller ramp designs that will permit extremely high
rpm with very high ratio rockers while offering the utmost in valve train
stability. Initial designs will encompass 254 to 268 duration @ .050 with .410
lobe lift. We already have added 280 & 284 with .420 lobe lift.
We are planning another open house. This one will be in the 1st
part of April but the date has not been finalized. We hope to finalize in the
next week or so. We will immediately post it on our web site. We hope to have a
few of our customer and vendors present several seminars on various racing and
street performance topics. We are
trying to schedule it just before the opening of the Stock Car Season at
Delaware International Speedway so we can have some stock cars on hand while
they still look new and fresh. We hope to see you here in April.
As always we
thank you for your support.
Yours truly,
Charles, Harriett, Clarence, Chuck, & Shannon
