Ignition box upgrade?
Hello all, I have a 1979 F-100 W/300 L6
I'm by no means a mechanic but I've been trying to do all the work on this truck myself. What I'd like to know is, what are my options for replacing/upgrading the ignition box? I have gone thru 2 of these cheap china boxes in the last 18months and now this one is starting to act up! So what do you guys recommend? Sorry if this question has been answered in another thread somewhere I did a search and read a lot of post but couldn't find what I was looking for...

mikeo0o0o0 usually has a lead on the OEM boxes, he should chime in here shortly.
There are other solutions if you are looking to get rid of the DSII setup too.
Are you sure its the boxes though?

I replaced the module on my '78 with a MSD 6A, since I was looking for a bit of an upgrade.
If stock will do, do as Mike suggests and install an OEM Motorcraft.
You answered your own question when you said "cheap china boxes".

MSD Blaster 5900 ignition box with a Blaster 2 coil. That's what I use. If you can't find it, the 6A and 6AL are boxes equivalent to the 5900 box.

Is it worth it to spend the extra cash on the blaster box and coil? are there any other upgrades id have to make if I went with this option? this is my daily driver and I want it to preform well but its no hot rod by any means lol

It should be a bump up over stock but not much at all. Should work with everything. If you have a points distributor changing it to solid state might help but other than that I leave it. I tried changing a 351W to duraspark 2 and gave up so I installed the blaster system.
Personally I'd trust MSD over even stock.

The only difference in a DSII is the larger distributor cap/rotor. It consists of a plastic adapter plate and the DSII cap that can be added to the DSI system. Your's, being a 79 should already be a DSII with the blue grommet module. As posted above, get the Motorcraft module. I will even by them used out of a wrecking yard when I come across them. For a stock engine, I have found you can spend more money, but the Duraspark works just fine and readily available.

Do you use this with the stock distributor? Can the stock distributor be used with any of the MSD kits?
