302 parts compatability
Hey guys, Im new to the whole V8 thing and I have a 1990 EFI 302 from an F-250 and I think it may need potential head/block work. I found a 302 out of a 1984 Ford Country Squire Station Wagon for really cheap. I have read that camshafts are different in the Mustang 5.0's but i wasn't sure about this model. Also I have heard that the newer ford engines (after 1988?) are different as well. I just needed some advice, as to if it would be worth getting ahold of as a short block to rebuild for this truck. Any and all advice would be worth it. Also, if anyone has any links to anywhere (other than ebay) for short blocks, preferably in central ohio. Thank you in advance!

If the cams are different the only thing that poses an issue is the firing order you need to use. 5.0HO and 5.8 motors have a different firing order than the regular 5.0. Your truck should be the standard firing order. The heads on that '84 302 won't be as good as your 90 heads would be, but it SHOULD be a bolt up install, and should have the same firing order as your truck. Also, the timing cover/water pump from the 84 would be different from the 90. Where at in central OH??

Thanks for the info! Im about 15 min. northwest of Columbus. I believe I have the standard firing order, as should the engine looking to be purchased. The cam could be changed out as well, right? The intake manifold, EFI and heads should be OK to bolt on? I have heard something about the water pump being different, too. Is that operation based or a different bolt up? Again, I appreciate all your help.
My experience has always been 4 cyl. Hondas, but they don't build a real truck!

Thanks for the info! I am in Marysville.
What makes the water pump/timing cover different? Would it be mechanical or bolt up? I have heard that there are differences in water pumps. Also, would the truck cam go in OK? I think it may, but im not sure. I would plan on using the truck heads if they were to work, and install the truck manifold and EFI. If all the truck electronics are going on the system, would there be a wiring harness issue? Im guessing that if I used the mechanical parts from the bottom end of the '84 engine and the EFI/Inake/Heads/(hopefully cam) from the truck engine, I should be OK. Is it worth finding out or going out and buying a short block...
Most of my experience is on 4 cylinder Hondas... but Honda doesn't build a real truck! (or a cheap one for that matter)

there is a manual fuel pump on the older engine, which bolts to the timing cover. you can still use this on an EFI vehicle but you'd need a block-off plate for that hole. Since you already have the correct cover I'd just use it. Yeah all the parts are bolt-on, heads, intake ETC. If you just use the short block from the 84 you'll have little to no issues, but use all the parts from the truck motor you can, oil pan/pickup included. It will be different

cool. That sounds like a plan. Here is what is going on with the engine currently. Obviously, it wont start. My girlfriends father was bringing the truck by the house (to sell me until this happened, now its free!), and while he was driving, it ran rough, and vibrated a lot. Then, holding the gas pedal to the floor he went 10mph, then stopped. I went out with my dad to tow it because it wouldn't run. We got it into my garage, and tried to start it, and smoke was blowing out the intake! I took off the manifold hose to the filter housing and there was oil inside the hoses and on the filters. I am wondering if this is a block problem or a timing problem, potential cyl. head problem, etc. and am hoping an engine rebuild would be OK. If the heads are good, i think im going to try to do a rebuild from either that '84 engine or a short block kit. If the heads are bad, I may be shopping for a while. Thanks! (where are you at in OH?)

i think you should look for 88-92 H.O5.0 vin E mustang/lincoln engine with forged pistons and roller lifters,steel cam,,,stronger block,,you can then convert easy to carb using a 1985 roller lifter application mustang distributor as that is the only year that was carbed and with the roller cam ,the distributor gear has to be steel,,,these engines can be obtained quite cheap ,id forget about the 84 its up to you thats just my advice,,then again you could look for a 351 for more torque

The truck is EFI and I am looking for the most economical way to get it running with good torque. I didn't think the HO engine would be that practical due to the fact that I would need a new ECU and probably a wiring harness. I know that engine is a better performer, but how would it do in a 3/4 ton F-250?
Ive considered the 351 but I think I would need a new ECU for that as well. I would think that engine would be a little more expensive and harder to find?
This truck wouldn't be a daily driver, just a means to move some things around and maybe pull a boat someday. My goal is to get it running decently for as cheap as possible. Thanks for all your input.

Hi chexx_mexx, and Welcome to FTE! Please take a moment to check out the Guidelines as they contain important info that you'll need when posting on the site:
https://www.ford-trucks.com/guidelines.html
I suspect that the difference in water pumps you are referring to has to do with the fact that the later model vehicles with a single serpentine belt have a reverse-rotation water pump. When Ford was just getting going with serpentine belts they seemed to use several different configurations. I had an '84 Lincoln Town Car which had multiple serpentine belts and still used a V-belt to run the smog pump. As I recall it had a standard rotation water pump.
