DIS info

[Chris Conlon]

Thank you to everyone who suggested intake manifold fillers. It
turns out McMaster-Carr has the Devcon stuff so I'm getting a few
pounds of the aluminum putty from them, and playing with some of the
other solutions as well.

It may not help too much but at least it's free: Go to the Motorola
web site (www.mot-sps.com) and grab the datasheet for the MC3334 .
It's a chip that handles most of a non-DIS ignition, but a careful
reading will give some good info about ignition systems. Actually a
guy I know is using 4 of these chips as part of a diy DIS system,
but I don't think it qualifies as being built from readily available
OEM or junkyard parts.

Actually it looks like

http://www.mot-sps.com/books/sg96/pdf/automotiverev15s.pdf

is an old summary of various Moto automotive bits. They also list the
MC33093, MC33094 and MC79076 as other ignition related parts, but I
haven't looked at the datasheets yet. Generally, tho, I find that
datasheets are often filled with juicy useful tidbits from someone
who already did your research for you. ;)

   Hope this helps,
