GM HEI Ignition Systems

|
This exclusive design allows
you to fine tune your ignition timing without pulling out your tool box. Each
complete 360 degree revolution of the thumbscrew adds or takes out 2 degrees of
ignition timing. (limited to 10* +-)
Perfect for the Street Rodder who wants to run a small shot of Nitrous or if
you need to make a long trip and want to run less expensive and lower octane
fuel you simply tune out a couple of degrees of timing to eliminate detonation.
We also build MSD and Street Performance module HEI Distributors, we phase them
and set the curve correctly to your engine and car specs.
We originally developed this distributor for a
Guy that wanted everything out of his car,,,a Highway Cruiser, Sportsman Bracket
Racer on Sunday and Street Racer on the bottle for Saturday night . His problem
was that he knew nothing about Ignition, didn't own a timing light and had to be
taught "Lefty Lucy and Righty Tighty"...there was a void here somewhere....so we
filled it.
Run N2O and you turn it counter clockwise 2 revolutions= -4*
Regular gas for cruising turn it back one turn= -2*
Race on Sunday on 103 Octane turn it up one revolution = +2*
If it pings go back 1/2 turn at a time until it stops = -1*
It's been 2 years now and the ignition has worked flawlessly, he's been winning
races at the track, making trips around the state and running whatever gas he
can find cheap....he just keeps dialling up and down to keep the detonation out
of it...so simple even He can figure it out.. I check it once in awhile to be
sure he hasn't got it all twisted out of control and he's done a good job of
following instructions and keeping track of where he's at with it...so far it's
proven to be idiot proof. As of 7/04 he's running is 4th place at the local
track and is a major contender for the Division 6 "Race of Champions"
So that's how it started and since we built his we were flooded with locals
wanting the same thing, we went to work and perfected the adjustment mechanism
for mass production, found a shop that could make a few hundred components and
we're ready to rock and roll.
We currently (July 2004) have about over 100 units in daily operation...no
problems, no failures, no warrantees and no returns, nothing but good reports
back from everyone. Since we started this producing this adjustment dial some 5
years ago their is a few big company's that have tried to develop a kit for the
do-it-yourselfer. We've looked at the kits and all we can say is "Get the
original"
You won't find this Original design anywhere else, this is not a dealer or
distributor item we hand build each one to your car specs.
Our Distributors are most finely tuned unit you can buy for your car, no matter
what brand you prefer you'll get noticeable gains in ease of starting, off idle
response, down the track or down the highway.
