5.0 Efi conversion w/AOD

[rkb76project]

I am putting a 1990 5.0 Efi and AOD in a 76 Bronco. I don't have enough room for the radiator and fan. Should I change to the Explorer/Mountainer front brackets and accessories or is there another option? What has everyone else done? Please email pics if you can. Thanks any help is greatly appreciated.

Did you move the motor mounts forward? What brackets are on the engine now?

No I did not move the motor mounts. I used the stock bronco motor mounts and engine brackets.

Are you using the Mustang Serp set up? What you describe should work, clearance will be tight, you need to use an aftermarket reverse rotation fan (18" I think...) You will have to shave down the spacer and there will be about 1 inch of clearance with the factory rad and shroud, with a 1/4" clearance between the tensioner and the back of the fan. Thats what I had in my 75...

There would be alot more room if you went to the Explorer set up...

1990 WHAT? I put an F150 5.0L & AOD in Frank's '75, and the radiator & fan fit.

i just did this swap and and used the mustang serp setup with a derale fan, 1/2" spacer, factory shroud with some work to fit and a 4.0 explorer radiator. works fine and has plenty of room. looks just like the factory did it.

I only have about 6" of clearance from the front of the water pump to the back of the radiator support. Is that about what you guys were working with? If I try the 18" fan is the explorer radiator going to work with the AOD and the stock lines, or did you use external transmission coolers and build new lines?

Marty, I see your power steering pump is mounted where the A/c compressor was. What kind of pump did you use and how did you change/modify your brackets?

I've been wrestling with these problems for a long time, thanks very much for everyones help!

Options
1) with a standard 3 row ( 2.25 inch) EB radiator it can be made to fit tightly with a proper fan and spacer
2) Cut the core support and move the radiator forward ( you can get about an inch to 1 1/4 inches this way)
3) Use Exploder serp setup.

4) Build something using a different radiator/core support

I just found out the explorer serp. is not an option. Since I live in wonderful California I have to pass smog. Explorers don't have a smog pump.

Does anyone know the difference between the explorer 4.0 and 5.0 radiators?

i used a saginaw/delphi pump from a marine engine with the serp pulley installed already. i purchased a bc broncos bracket by accident from what i remember and just made it work with some small spacers and i then made a rear bracket out of some miscillaneous brackets i had around the shop that i could weld up to work.

That doesn't matter. The presence of a smog pump is only required for older catalytic converters. Modern replacements contain chemicals that store Oxygen from lean exhaust and use it to clean rich exhaust, so no 2ndry air (smog) pump is required. Get new cats, keep the engine well-tuned, and you should pass the sniffer. You'll never pass a visual, but no inspector will know what should be under your hood anyway. Not even Ford could tell you what they put there 40 years ago.
