GM HEI mopar dizzy hybrid
Myself I run a stock module. I have never read anywhere were the performance ones are better. I know there is a fancy new one coming out that has a rev limiter built into it.. For the money a stock one does great IMO.
This is the case as far as I can tell also.
As far as I can tell the aftermarket "Performance" modules are not genuine GM parts, so I personally believe they are probably Chinese made and not as reliable.
The ONLY reason I would use an aftermarket module in my 8 pin HEI system was if I wanted the rev limit function of the Ignitor 3.
Problem is, that it would require a modded, aftermarket or OEM points distibutor to run it, because they don't make one to fit inside our OEM electronic distributors. (The Ignitor 3 HAS to be inside the distributor) because it triggers off the distr rotor.
I'm almost positive the ignitor 3 is a Hall effect triggered system, so there may also be issue's there, but they do advertise it as able to replace points.
At classichei.com we have been on the hunt for an HEI capable system with rev limiter inside an OEM distributor for $200 or under but it isn't looking good yet.
Once you add the price of the replacement distr and HEI capable coil that puts it around $250 if a person did it themselves. (beyond that in cost and you might as well buy and MSD box)
