Hello, I'm from the Central Texas area and have had 2 broncos in my life but grew up around them, you could say I'm from a bronco family. my First vehicle was an 83 Bronco with a 351w and C6 trans the truck wouldn't die no matter how hard i was on it hell she got the nickname Aquahorse since it was underwater more then on the road. unfortunately i had to sell it when my daughter was born. However, I recently inherited my dads 93 bronco after he past last March, she going to be a lot of work to give her what she deserves. My dad blew the motor back in 2009 and the truck has sat since then. from what i have found so far looks like the #3 rod gave and had then piston and head meet. The truck is in rough shape due to sitting for so long and the fact he didn't do the proper upkeep while he had it. My options as of now are to ether order a Long block 302 and do a new clutch and cooling system for good measure, or drop in a 300 I6 that i have from a 91 F150 that is in good shape but has been sitting in my Garage for 15 years waiting to be bought back to life. The question is how to run the wiring if i go that route due to the engine being an EFI motor, I know the transmission will bolt up since the one in the is out of the 91 F150 the motor is from. Has anyone done a backwards swap to a 4.9 from a 5.0? Also anyone now a good way to get mold and tree sap off a white top?

Yo Koond93,
WELCOME!
91 5.0 swap to a 300 w/carb using an E4OD & Quickshift trans controller
with pics! by Brad613 @ https://www.fullsizebronco.com/forum/15-general-discussion-bronco-wheeling-related/234994-ford-300-4-9-engine-swap.html
BTW you will need the engineering harness from a yard queen's 4.9

"my bronco is in the middle of a 302 to 300 swap. I probably wouldn't trade a good running 302 for a six. but since i got mine back with blown engine and torn up front clip, its wasn't that big of a deal. mine is getting a megasquirt II controller and a dual range aux tranny so i can keep it running in the sweet spot. it's not meant to be fast, just reliable and efficient. plus its easier to work on and looks sharp for not even being complete yet.

the bellhousings are the same between the 302 and 300, but you need to use the 300 specific flywheel because the balance is different. radiator in/out is different, see motor mount pic below.
and its the passenger side mount thats different, but if my memory serves me right, theres no rivets, it all bolts in.
See pics.

Steve wrote In response parts needed for 5.0 to 4.9 swap;
"I'm basically doing this swap right now, transferring my '83 drivetrain into the '93 body & frame.
Engine perches (on the frame), radiator, engine bay wiring harness, Y-pipe, coil springs (unless you "ballast" the V8 coils with a heavy bumper ), forward fuel lines, throttle & cruise cables, air filter hoses...
The driveshaft lengths are NOT related to the engine - the trans is always in the same place, so d'shaft length is only related to transmission model, 2-/4WD, & wheelbase.
All smallblocks use the same bellhousing pattern, and only smallblocks were used in these trucks as EFIs, so any trans that fits one EFI 1/2-ton '87-96 engine will fit any other. Some '95 4.9s were MAF, but all '96 engines were MAF OBD-II." In post #11 @ http://www.fullsizebronco.com/forum/...-4-9-swap.html

"...can you just grind the weight off the 5.8 flex plate and use that on the 4.9 or is the crank pattern different?"
"I have no idea. I'd never try to bastardize an engine like that. When I do an engine swap, I get a COMPLETE engine, and install it the way the factory did (just, in the wrong vehicle ). I've only ever put a 4.9L flywheel on my 4.9Ls, and 5.8L flexplates on 5.8Ls. I've never compared them - it wouldn't have even occurred to me, if I had ever had both apart at once."

Yo,
Find out if speed control, if equipped, recall work completed by a dealership. Call local dealer or register and view status @ https://owner.ford.com; or @ https://vinrcl.safercar.gov/vin/ ... have VIN ready.
The affected vehicles were previously repaired using a wiring harness that is not compatible with the vehicle circuit polarity. As a result, the fuse is located in the output circuit rather than in the intended input power feed circuit, and may not offer the intended protection in the event of an electrical short to ground. This could result in an underhood fire. Dealers will install a new wiring harness, or replace the mating electrical component. east302 provided following for his 93 "I found the recall information on alldata...didn't know it was even there so that's a plus. Mine has the updated harness with two fuses instead of one, so it looks like the recall was addressed correctly."

Note that the 93 recall is different that the other years.

Thanks for the reply Miesk5, Ill have to take a look into the recall, I'm not sure if it was completes but luckily there hasn't been any fires under the hood yet. (knock on wood). The info for the 4.9L swap is really going to help, I have thought about going with a simple points and carb set up or a stand alone ignition with carb, unless I find a donor harness and ECM. I Plan to start the tear down in April after i get some cash together, Ill start a build thread at that point. I do want to keep it as reliable as possible I'm not going to be making this one an off-road only truck like my last one, I plan to turn it into a good rainy day and weekend camp/ trail truck.
