I running a rebuilt 455, Edelbrock performer rpm set up carb (750cfm) to cam with a new Billet high performance HEI distributor from Jegs (says it produces 50,000 volt spark through 7500rpm. It has a High perf. adv curv, coil, and cap with brass terminals. My question is would I benefit more from adding a MSD super HEI kit from Jegs with a MSD 6AL box (p.98) or should I just go with a MSD 6AL box. the price is about the same, but do I need all the Super HEI stuff with my current distributor? Thank you in advance.
