Let me preface this by pointing out that I have a very general knowledge about mechanics, I've done industrial machine maintenance for a few years, I don't know automotive mechanics. An example is that what some people call the choke plate in the carb, I refer to as a butterfly valve (because that's WHAT it is). So when things like spline counts and flywheel teeth come up I know what they are but not what you mean. Ok I'm pulling the 302 out of my 93 bronco. I know I need all the wiring and the computer. Right now I'm at the Research and Planning stage. What do I need to pull besides the Engine, Wiring, ECU? What do I need in regards to a fuel pump. Ive seen some things that say I need to put in a surge tank connected to the old fuel line and build that with an in-tank pump and regulator? This sounds overly complicated to me. Anyone have other suggestions. How much of the truck exhaust is probably re-useable? I'd like to save a little if I can. I know the flowmaster muffler is good. What should I do to the engine while it's out. What other simple upgrades should I do. I was thinking of getting some GT40s for it. Theres a ton of explorers in the junkyards here (had some ice the last 2 years so there are like TONS of explorers for real). Any help appreciated. I've got way more time for this than I have money for it. So I'm spending lots of time in research and planning to set a realistic budget. Just thought of this but I don't suppose the rear axle would be swappable?
You will need to swap the truck oil pan for a front sump car pan. You didn't mention the transmission. The imbalance factor for the 93 302 is different from a 70's 302. The 93 uses a 50oz/in flexplate/flyweel (automatic trans/manual trans) It will also be larger in diameter than those used on a 70's Maverick/Comet (if you're using the transmission for a Mav/Comet) Virtually none of the truck exhaust is useable, other than maybe the manifolds, and even they may not fit the car. As for the fuel system, all that will need replacing to a high pressure system. I don't know about the fuel tank, it may be too shallow to fit a pump in. If it were mine, I'd just carb the 93 motor, upgrade the roller cam to something bigger (it'll have the smallest of the small roller cams in it with it, you're looking at everybit of 150 hp. Just changing to a 94's cam will net you 50 hp.
you will want the fuel lines. there is a fuel pump on the frame rail and a fuel pump in the tank. take both of them. the tank pump is in an assembly that you can adapt to your stock fuel tank. you will need to change the oil pan and oil pick up to a front sump style. thats where the bulge of the pan is towards the front of the motor. the throttle body (butterfly blades) of the truck intake will interfere with the hood. joedirt put one of these motors in his car. http://mmb.maverick.to/showthread.php?t=52555 his thread should answer allot of your questions.
So I may want to pull a different throttle body then? Any suggestions on vehicles to look for that on? As far as transmission goes, I'm going to find a t5. The truck transmission is 4x4 and not really likely to fit under the comet. Looking for less obvious stuff. Don't hesitate to offer up things that need to be changed about the engine.
You'll need to not only change the throttle body, but the whole upper intake too. And unless you can find a Holley or Saleen upper, you'll have to replace the lower intake as well. The lower matches the two I listed above (the Holley for sure, the Saleen, I'm pretty sure of) The truck lowers don't match any of the O.E. car uppers
Yes. As would the whole motor, with the exception of the oil pan and exhaust. You surely don't want the exhaust from one.
I already have the bronco, I suppose I could try and sell it (havent gotten any interest when I tried before) but for now I'm stuck with that engine.
Somewhere in the late 80's early 90's they ditched the frame mounted fuel pump. I'm not sure about the 93 but the 94 I killed only had the tank mounted pump. Get a wiring manual for the 93 so you can sift through the tons of wiring and get only what you need, keep the entire harness though, the scrap yards pay pretty decent money for what's left! I am switching the truck intake on mine for the Explorer set up with a 65 mm throttle body. Make sure that you get all the data off the door pillar if you plan on staying with the original computer, it will help if you ever need to do some serious diagnostics. The fuel lines will not even come close to working in a Maverick so you need to just start fresh there.
All great information. Since you are in Portland and have time, you have an open invitation to take a ride to Blue Oval in Vancouver, inquire and observe my 1996 Bronco being completely overhauled at present covering most of your questions. Although it is a 351w, speak with the crew on what I am doing to gain insight and ideas, first hand. I anticipate this aspect of the project finished by months' end...
So what kind of cam would I need? So let's say I'm in the junkyard raiding an Explorer, would I want to pull the cam too?
Yes, the Explorer cam is pretty good, only a slight step below an HO cam. It's even better if run with 1.7 full roller rockers. This same cam was also used in the 94-97 trucks and vans with the 5.0 and 5.8. Specs are 256/266 advertised duration, .422/.445 lift (1.6) .445/.473 with 1.7's. The HO cam's specs are a little fuzzy, the duration is either 276/266 or 276/276 with a .445/.445 lift with 1.6's. Both work great with carbs too, if you decide to go that route.
