ok so the motor is a 333 stroker has just a little work done to it like aussie heads edelbrock intake,etc nothing major but i also have a plain jane 302 with just some aussie heads and eagle piston (i think) with about 300 and something horses so do u think that will do good on a conversion because my 5.0 is just a piece oil leaks all the time now about every week or so something else is wrong with it like distributor caps, the starter, the alternator, battery is dead, U joints, brakes, it just is costing alot out of my pocket so please help me out on this i really need it

I say get a HEI distributor. They can be found a broncograveyard.com. All you have to do is hook up one wire, the the brain box for electronic ignition and coil is built into the distributor. Looks very nice cause it cleans up the motor.

I recommend using Ford's duraspark ignition. You can keep your original coil, plugs, wires, and cap. All you need is a duraspark distributor (1983 5.8) and module. which can be had for less than $100.
You can make your own wire harness or grab one off a pre-1986 truck, car or random 1975-1991 ford, AMC, or Jeep product. It is HEI and basically plug n play. Looks stock if you do it right as some heavy duty Fords up until 89 or so came with this from the Factory.

Yeah same here, Like the idea of EFI for so many reasons, Sure carbs are fun but when I want to jump in the truck and go EFI is no brainer. Will be going with edelbrock's pro flo 4 EFI in spring almost everything is in the box as well (minus your coil and fuel system ie pump hoses ans regulator but still alot more complete then most of the setups like FITECH and Holley's Sniper EFI which is basically an electronic carb.)

Yeah I feel the same way, but I understand some people don't have the money or tools/equipment and knowledge to fool around with kaput EFI system. It's just easier for them to revert these 1960's design engines to carburetor. For a show queen or daily driver? --No way, but honestly not a bad option for a clapped-out farm truck.

You can can fiddle with a carb and get them to run very good but it will still need periodic rebuilds and maintenance. How much time do you spend on your ‘96 working on get size, idle mixture and choke adjustments? Sequential fuel injection is much more precise than a carb could ever hope to be. I have carbureted vechicles but they are not my daily driver.
To Zbrown that brought this thread back from the dead,
What testing have you done? Did you just throw ignition parts at it? Are there any fault codes stored or active?
