I am buying a 1992 302 engine and I wondered is it just like the 302 in my 74 fore bronco? someone said something about the dipsticks being in diffrent locations. Also it is fuel injected, how hard is it to swap it over and is there any articles out there that show's how?
thanks!

 

It depends on what application it came from. The dipstick in the Bronco goes into the pan but on the later engines, there is a provision in the block. Most opt to use the Bronco oil pan for clearance (and plug off the hole in the block), but a rear sump pan from those years would fit with a suspension lift.

As for swapping the EFI into your Bronco, it depends on whether it is a car or pickup application. Either system can be adapted pretty easily, but there are hood clearance issues when using the truck intake.
There are several posts in this forum for EFI swaps. There are a few of us here that have done these conversions and can help you with almost any question you have.

Here is a couple of good articles:

I have found a ford 302 car engine out of a 87 marquis and I was told that my 74 bronco pan would not fit on the car engine. Is this true?
thanks

 

No, the Bronco pan will fit. You would need to cut the dipstick tube off flush at the block or completely remove it and plug the hole. I used silicone to seal mine.

why cut the dipstick?

 

Can I use the alternator, power steering pump and serpitine belt on the newer engine and leave it balanced the way it is?

 

you are just going to do away with the dipstick and tube in the block, you will use the bronco oil pan and it has the dipstick and tube in the pan instead. that is what he is trying to tell you. how you do away with the one in the block does not matter, cut it off, pull it out, ect. you just want to block it off so it does not blow oil out of it.

and yes you can keep all the late model belt drive and keep the balancer so your balance stays the same. dont forget to use the correct flywheel to keep your balance correct also. the water pump pully spins the opposite of the late model also so your bronco fan will not work. be sure to get the correct fan blade also or go electric. the 87 marquis fan does not have enough clearance between the water pump and the radiator to work.

 

Sorry if I wasn't making myself clear. The dipstick tube needs to be cut off or removed because it interferes with the Bronco oil pan. The later pan has a small bulge in the rail to clear the tube.

To add to what Spartamouse was saying, the water outlets are reversed on the late model engine. You would need to change the outlets in the radiator or come up with a custom hose setup. Should be the same as the Mustang, I can get you the specifics on what you would need. There are a couple of Bronco parts suppliers that can come up with the right reverse rotation fan for your needs.

The flywheel you need would be from an 85 or later truck 302. If you are running a manual transmission, you will need to modify the clutch equalizer engine mount as the late model engines are missing a bolt hole. It's a very simple fix though.

Would you mind getting me the specifics so I will have a parts list and get started on this before summer gets here. I, (tell me if I am wrong) would like to keep the one belt assembly and I am sure that the alt is a lot better than the one on my Bronco. The bronco is a automatic. Can I use the balancer thats on the car motor?

This guy has two engines. One is in a car that runs and the other is supposed to be out of a police interceptor and it is setting on the ground. I can buy the one in the car for $250.00. Or both for $400.00. I thought about buying both, installing the one that runs, and building the other.

 

If you choose to keep the radiator outlets in the stock location here are some options.
For the upper hose use a upper hose from a 68 GTO with a 400. You will need to trim about 1" off of the water neck side and 6" from the rad end.
For the lower hose, there are several different ways to go. Take a stock Bronco lower hose, cut the ends off and install them on the radiator and water pump and then do some measuring and simple mock ups to take to a muffler shop or fab shop to bend some 2" pipe. Ideally, you want mandrel bent tubes so that the diameter is the same throughout the bend.

For a fan, the Flex a Lite 1517 works with a 1" fan spacer for most applications. If you have an aftermarket 4 core radiator, I've heard of some clearance issues. If you're not planning on running a smog pump or the A/C pump, you will need to get the eliminator brackets for them. The last I had checked, they were still available through Ford Performance Parts. If you choose to go with the serp belt set up you will need to use the balancer from the car engine. You can use the alternator on either the serp or the v belt setup by just swapping the pulleys. To change to the later model alternator, you will need to change some of the wiring and add the late model voltage regulator. Unless it is rated for over 100 amps, I think you would be better off to upgrade to the internally regulated 3G alternator. I wish I would have done it on mine.

What about the fuel pump

 

If you're going to stay with a carb, you would need to change the front cover to for one with a fuel pump mounting boss and install the fuel pump eccentric on the cam. Or you can install an electric pump.

If you're going with EFI, you can either buy a fuel tank that is set up with an in tank fuel pump or you can run external pumps. One low pressure pump (Federal Mogul P4594) to pull fuel from the tank(s), and a high pressure pump (Federal Mogul P74028) to supply the engine. You also need to plumb a return line back to the tank. If you have dual tanks and plan on keeping both of them, you will also need an electronic switching valve.

What year frount cover. Will the frount cover offf my 74 302 work?

 

Yes, the front cover from your 74 would work. But, you would have to run the standard rotation water pump and your old accessories. You would also have to get a different balancer that was balanced for a late model engine with the offset and bolt pattern for your Bronco's accessories. I paid about $70 for a completely rebuilt early balancer with the late model imbalance.

Some early 80's cars with 302's had serp belts, RR water pumps, and had mechanical fuel pumps. With a little junkyard searching, you might be able to find something that would work.

I need a flywheel for a 85 ford 302 with a C-6 automatic transmission right?
