new ignition advice

I'm swapping my tired 400 for a 351W and I'll need a new Distibutor/ignition system. I'm looking for better MPG and dependabilty. Any advice to get me going? '81 F250 4X4

When I got my 351W I was told to ask for ignition system from an '85 Bronco, DuraSpark II ignition.

The two system I've been looking at are the DUI from Centech and Jacobs. Any word about those, good or bad?

I have heard the dui is a good piece, who can argue with a clean engine compartment (no additional ignition box or coil scattered around) and one wire hook up. There have been a few people on here that have went with the dui or a similar unit. The jacobs is fine as well from what I have heard, kinda pricey though. I have only had experience with the duraspark II and msd and like them both. later

I went with a GM style distributor with the coil in the cap, and one wire hook up, I can't think of the name of it, but it was around $200.00, and it works fine.

I would second the DuraSpark II ignition. It's cheap and very dependable. I can't say that the others may out perform the ford set up but I bet the ford set up will out last all of the others. If you break down, you can get a replacement part any where if you have the DuraSpark II ignition set up.

The total cost would be around $50 for a new dizzy plus a core and $20 for the module. I run this same set up on my 400hp 65 mustang and had the same set up on a 70 mustang with a 460SCJ motor with 550hp. The 460 ran great until I ran it at 8K once to many times. Man that was a big smoke screen when it let go.

Thanks for all the info, I ended up getting my 400 rebuilt and switched from a 2b to a 4b which means a new carb. Now my pocket book hurts so the update on the ignition system will wait. I'll share my experience when I'm done.
