The least expensive would prolly be the Nutter by-pass (I don't know if those had a computer or not), combined with the Ford 300 ci distributor cap and rotor, and the MSD Blaster 3 coil.

Or, you can consider upgrading to a late model GM HEI distributor. I think you can pick those up for pretty cheap as well.

You would need the distributor from a newer 258. Rest is the same.

First of all the Nutter Bypass is for computer controlled Jeeps. Not applicable to a '74.

No matter what upgrade you do you're going to have to replace the distributor. With that in mind the easiest upgrade will be to go with GM HEI. It's a one wire hookup as opposed to several wires and an ignition module with the '78 and up Duraspark (Motorcraft) system. If you already had the newer setup, the TFI upgrade would be the way to go.

Now if I could just find Larry Maggio's HEI upgrade webpage to give you some part numbers and install info.

Found it: http://www.geocities.com/jeeperaz/hei.htm

Stay away from DUI unless you want to pay over $300 for something you can build yourself for $100.

true on the money - but it comes to time..

I build all my stuff but pick n choose my battles for time. The dist at the auto parts store was $150, then ya gotta buy the rest. I do think you can save but for the $75 - $100 saving and the loss of time I but the bullet. Mine is a tad more rare, I have a buick 225. The DUI is cheaper for this one too for some reason, course shipped etc it is still 3 bones (the others are closer to 4!). I don't doubt it cost more but ya gotta splurge sometimes, plus there is the brag factor

I found the HEI distributer in a local junk yard for $25, and just ordered the drive gear from 4WD for $24.99 plus shipping. Between the wires I got with the distributer, and ones I have lying around I'll be able to make something work. Add to that a new cap and rotor and I'll have a pretty good ignition for around $75. I'll post as soon as I get it all finished to let you know how it works.
