Do i need an MSD Ignition kit, or can I use a stock 440 ignition, dist, sparkwires and plugs?

I'd recommend an MSD with a rev limit. I've used 2 digital 6 units and I really like those. They let you have 2 rev limits and a timing retard.

While I haven't used one the HEI units seem to have a good rep.

I'd stay clear of the orange box, chrome box etc. Can they work? Yup.. Antiquated technology though and every car I've had one on has failed me at some point. Wither the box failed or the ballast resistor let go. MSD eliminates the BR.
