HEI style distributor cap

I think he meant HEI style as in with the male connectors for the wires at the distributor. You'll get a more solid/reliable connecton at the distributor. I havent had any problems with it, but it is something that could be improved upon (from stock).

And if he did mean HEI ignition, i think i gotta link for that too. Hate to say it but GM did have their ignitions down with HEI, Chrysler wasn't the best and most reliable with their ECUs. 2cents
