MSD Install While Keeping Orange Box?

Touché! However I do believe Greg mentioned you can add a rev limiter to his setup. Still worth the upgrade and increase in performance and efficiency and decrease in number of wires running everywhere! But I digress, and will try not to get/stay off topic

Yes but that costs more money....I will agree though the HEI system does have a strong spark....For what the poster wants though, which seems to be a Rev Limiter and ease of switching back and forth if one breaks down on the road ( And also said nothing about cost so I assume price isn't a concern).....I said the REV-N-NATOR because one screw out on the plug and screw it in on the other and away you go
