My 72 GTS has its original 302 V2 and C4 tranny. Runs great, just gutless. lol
I know I could build up my 302 and probably come close to tripling the factory HP. But, I do not have the tools or skills for anything beyond basic maintenance and changing bolt on components. i.e. alternators, sparkplugs. etc. With that in mind, I am considering finding a more modern fuel injected engine that I could have put in and bolt up to my C4. I have been told that the Ford 5.0 through about 94 will work. What about the Ford 5.8 that can be found everywhere in wrecked trucks and vans? Is that just a updated 351 Windsor or something completely different? Thanks, Mike

Yes, the 5.8 is just another name for a 351W. If you can find a junked '96 (and maybe '95, not sure) truck or van they should have a roller cam. The serpentine belt system could also be used. If you snagged the wiring harness, computer, etc. from the donor vehicle you could use the fuel injection set-up and the overdrive trans. You'd also have to gear up an electric fuel pump. Not sure about the oil pan but they are readily available. Doesn't seem like that bad of a project but then again, I've never tried it.

The 5.8l efi intake manifold might present packaging problems as it is very tall. You might want to take some measurements (unless you don't mind cutting the hood).

302 has a short stroke and can wind up pretty quick setup right. With all the expense and retrofitting you would need and since you mentioned you were going to source the job out I would consider having the 302 built. Add some headers to it and if you haven't change out the rear end gears to something more performance ratio'd. Might also read up a little on the 347 stroker.
I have had terrible experiences with the C4 light duty tranny but again changing the rear axle ratio will reduce the stress on it a bit. Half the fords I had that got "doggy" had a slopped out timing chain causing the cam timing to lag. Distributer of course can be adjusted for spark timing but a delayed cam will make her sluggish sounding like it is doing something but no go.. I have had good luck on a budget with 302's setting the timing chain cam 1 tooth advanced then get some decent dual open flowing exhaust. |

Oh I forgot to mention. A easy way to check timing chain slack is simply to pull the dist cap. then get a breaker bar or whatever is big enough onto the front crank bolt turn the crank until the dist rotor turns then watch the rotor while you turn the crank the opposite direction. this will give you a idea of how much timing chain slop you have. If it has the original chain and gears the gears are coated in nylon ford claimed to made them run quieter but wore down faster as well. If you have those yet I would drop. Most of them failed with the nylon cracking off and timing jumping.

If you decide on an EFI setup, the '83-85 CV had a carb style EFI. Not a good choice. Later 5.0 engines from a Thunderbird (shorter intake) is a good choice, or a van 5.8 setup. Truck intakes are way too tall for our cars. Best bet is to find a donor, get all the wiring, sensors, AOD, CPU and all accessories. Much cheaper, you will have overdrive (great when a shift kit is installed), run an electric pump (or retrofit an EFI tank and you will be rewarded with more power, better driveability, better MPG, and a nicer all around experience.
