I've put in a couple Crane systems, it's late and I can't recall the model, but they have a nice adjustable rev limiter feature, and you can get an optical trigger set up for the pre 3.0 distributor and eliminate points. I don't know what you've got to do to hook up the 3.0 distributor, as both the installs I did were on earlier engines.

From beginning to about 1977 points were used to trigger a 3 pin CDI box. Passes less voltage thru the points .... last longer.
In 1978 with the advent of the 3.0L ... the distributor rotates in the opposite direction and magnetically triggers a 6 pin CDI box. |

QUOTE(rfuerst911sc @ Jul 25 2008, 06:34 PM)  I purchased model # 6853M but no tach adapter but I'm replacing the 4 cylinder tach with one out of a 911 for the six. To my knowledge one isn't needed. My mechanic has installed many MSD's and says most of the time a tach adapter is not needed. I don't fully understand the electrical requirements converting the 4 to a 6 but I'm leaving the wiring up to the mechanic. I also purchased a 6853M for my 911 but haven't gotten around to installing it yet. My hope is both cars will be running the Mallories and I'll keep the OEM Bosch 6 pin CD as " backup ". According to the website you need a $110 tach adaptor for the VDO gauges... I hope thats wrong... (IMG:style_emoticons/default/dry.gif) http://www.malloryperformance.com/pdf/6852M_6853M.pdf |
