Yes, as Dave points out the Pertronix is an alternative and I DO mention it on my website:

  Quote: >>Another electronic ignition upgrade alternative is available from Pertronix, Inc. Their Ignitor electronic module replaces the points and fits inside the stock distributor, retaining stock appearance. <<

Two additional points worth mentioning about the Pertronix: 1) They are available in "Marine" rated versions, including optional marine coils and 2) The Ignitor II offers several advatanges over the original Ignitor, including: a) support for higher output coils, b) auto-shutdown senses if ignition key is accidently left ON, c) auto-dwell sensing for 3X better output performance in the 3000 to 5000 RPM range.

Petronix also offers complete range Marine Billet Distributors for the small block Chevy, as well as Rev-Limiters and MSD-like multi-strike ignition modules.

Over the winter, I installed a Pertronix II in the my Chevy which uses the original OMC-supplied Mallory flat-top marine distributor. I also upgraded the original coil, spark plug wires and put in a set of NGK Iridium (XR51X) plugs. The goals are: no more ballast resistor needed, no more fussying with points/dwell tune-ups, better extended trolling (low-speed) by running a hotter spark which should reduce plug fouling, and maybe a tad better mileage & performance. Installation was easy (about an hour) and I'll let you know how it turns out. If I recall, Summit Racing got mine here in a day or two.

If you do install a Petronix I or II, save the old points plate, as it could be re-installed, in the unlikely event the Petronix electronic module fails

    Hi BC and welcome.

    It's been a couple of years since I had my Buick with the HEI. As I recall
    my buddy had to grind away a minor amount to gain clearance for the HEI from
    CRT. I've since sold the Buick, so I can't look at it. But it wasn't much
    that was required.

    I can't tell you either, as I wasn't present when he did it. But he had a
    shop and probably removed the thermostat parts to do the grinding.

    Hope that helps.

  Hi BC,

  There is another option. I installed a Pertronix Ignitor ignition kit and high performance coil in my 155 and they work great. The kit replaces the points in the distributor with an electronic trigger. Since you're not changing the distributor, there are no clearance issues to worry about. Make sure you order the kit for the odd fire V6, part # 1164 I believe. You should be able to get both the kit and coil through JEGs or Summitt for around $100. The web site is
