I have 502 modded with dart heads , dart intake , 800 holley , crane cam and gill exhaust. Im still using the stk ignition. Will I benefit from a msn ign? If so , how? thnx sj

= bigger boom ; Gellner has a demo in his shop, WOW! MSD Ignition systems are definitely intense. You have alot of mods done to your engine, an ignition system upgrade would be the next step to your bolt ons. I run all MSD on mine and have been very happy with the results.

I did a search... sure lotsa guys saying the msd is no gain over stock??? sj

Not like you are going to gain a tons of HP but supporting the mods that you have. It would help make the engine definitely more efficient.

IMHO if your aren't spinning your engine over 6000 or have a blower motor , I seriously doubt you'll see much difference.
Plus the reliability factor of a T Bolt is a real plus.

MSD is not going to show up on a dyno sheet as very much or in seat of the pants feel, but it is going to help make any performance engine have a better stronger ignition system.

Or maybe the best way to see if it does anything, is to look at every form of racing, NASCAR, NHRA, etc. These guys have unlimited funds to build engines, and they ALL run MSD. If it didn't gain them something, it would not be there.

I would not run a motor without one.......The amount of zap a msd distributes in unreal, plus it will make a tuner a lot happier.........Make the motor happy get full billet msd.....Also if ya get the 6al box you now have a rev limiter and you can get crazy with prop selection
