you need to make sure you get a "standard" HEI, not one that has the ESC. (Electronic Spark Control) You need one that has vacuum AND mechanical advance ONLY. I'm not sure if you'll find one of those in a V6 though, I think they all had ESC. What you need to do is get a standard V8 HEI dist and replace the magnetic pickup with one from a V6 model. I am not 100% sure, but I think the standard V8 module will still work just as long as you use a V6 pickup.
