Do not use anything from the HEI system. Please, remember that HEI was designed for a time when 5500 RPM was high RPM, and 300HP was a lot.

Buy an MSD distributor and put the Comp poly gear on it, all your distributor problems will go away. It plugs straight in to your box, no place to have a problem.

The MSD 7AL 3 simply has all of the rev limiter features built in. It has a burnout limiter, a stage limiter, and a high side limiter. If you do not need all of that, then consider a different 7AL.

Get the Pro Power HVC coil, it works great with the 7 series ignitions, without problems.

I've been through all of that. We fought the "mix and match" ignition BS for a year, then we took all of the crap off, put a complete MSD system on, and we do not worry about ignition problems anymore. Put in a matched integrated system one time, and be done with it all. No compatibility issues, no guessing, just race. It's a great feeling.
