MSD distributor vs original electronic distributor

I am being offered a pretty new MSD distributor for my 76 F-100 with a 390 for $150. The guy said it was only used once for about 20 minutes while he moved his truck and is now parting it out. I looked at it last week and it looks new and is in good shape. The MSD model is: MSD Ignition 8594 - MSD Pro-Billet Distributors - Overview - SummitRacing.com Now my current distributor is the original electronic model with the vacuum advance that has been recurved to my truck specs. The question is would this mechanical advance distributor be ok to run in my truck that is currently using vacuum or would the vacuum / mechanical model: MSD Ignition 8595 - MSD Pro-Billet Ready-To-Run Distributors - Overview - SummitRacing.com be better for performance? Any advantage of either one and would one of these have to be recurved?
The MSD isn't going to get you anything that your current system doesn't. Does it plug right into a Duraspark, or do you get an MSD control box with it?
You'd probably have to recurve it to meet your engine and truck, or at the very least, check what it's set to and decide for yourself, especially since your existing distributor is already customized.
The lack of vacuum advance may or may not help you - in a truck, dunno. I can't speak to that, since I always ran without it for the most part.
If it's got the box and everything, it's worth it. I had a Duraspark on my 390, and it ran "ok". Went to an MSD box and it woke the thing right up, especially cold.
OK, I met the guy yesterday and he only wanted $125 for it plus he also threw in an almost complete fel-pro engine gasket set. Next will be to take it to a performance shop and have them recurve it. Thanks for the help.
Orange, if you can get it for free, go ahead and do it. It isn't worth anything, however. The MSD distributor has a bad habit of burning up their magnetic pickups. The Ford Duraspark dizzy doesn't seem to have this trouble. I'd run the MSD coil and control box, but keep the factory distributor. At least carry the stocker around in the toolbox, just in case the MSD strands you someplace. IMO, worth zero. The gasket set would be good though........ DinosaurFan
Many "serious" FE folks, drag racers and such, use the Duraspark with an MSD box instead of the MSD dizzy, there's couple guys who are masters at rebuilding/ recurving Ford dizzy's, one leans toward restorations while the other goes more to the performance end. There's a harness available to connect the Duraspark to the MSD box, most bang for the buck is the Duraspark with an MSD 6AL box that has the rev limiter. The performance gains come from the proper curve and the multi-spark MSD box, not which dizzy you use
