Default Re: HEI vs Pertronic pointless ignition systems

No question HEI delivers a hotter spark than Pertronix, even if you use their 'Flamethrower' coil. I went with Pertronix for the stock appearance and I was concerned of clearance issues with the stock air cleaner. Never measured, will HEI work with the stock air cleaner?[/QUOTE]

Bob, When I get home this weekend I'll take some measurements on my 68 with HEI. I also have a 67 351E air cleaner to make the comparison. You are running the Holley 500 carb, right?
