I have an '86 Ford Bronco with a bad 302 in it right now. I am in the process of doing a solid axle conversion on it right now. Going to be running a Dana 60 front axle and a Dana 60 or 70 rear axle with 37 or 38" tires. I will probably run 4.10s or 4.56s depending on which tire I chose for the initial buildup.

Right now I am in need af a "high" hp 302. I would like to run one of those crate motors at 345hp but the $3000 price tag doesn't excite me the most.

What I want is 270-300hp at the rear tires.

My question is how do I achieve this? Do I stick with the stock fuel injection (is it capable of handling this task) or should I opt out on a carbeurated set-up, or convert over to mass air?

I was on the edelbrock web site earlier tonite and found that with running the full performance package they were talking of making 367hp with a carb.

So what do you guys think? I'd like to stick with the Overdrive tranmission in this vehicle, but I know nothing about it or what model it even is. (I haven't taken possesion of the Bronco yet), or would I be better off going with the C6?

Sorry for all the questions but I want to build this Bronco the right way.

 

Are you planning on off-roading? I'm thinking the solid axle conversion means you're looking at making this thing a rock-crawler.
If you are, you need to look at your drivetrain a lot differently, and stop talking about Hp. It's all about torque.

Without a high performance torque convertor, tranny, and center diff, you'll never get the performance you want from a 300Hp engine.

So unless you're ready to break the bank, I would reccomend pulling the 302, boring, fresh pistons and rings, maybe an Edelbrock FI intake manifold, perfomance fuel pump and coil. New clutch while you're at it.

Ya this is going to be my beater/hunting/rock rig. Initially I was planning on building up my '99 but decided against it for the obvious reasons.

It will see lots of mud, snow, and rocks when we go to the Bighorns elk hunting or the Black Hills in SD.

I decided today against the 4.10s and will either be going with 4.56's or 5.13's. It will see minimal hwy use.

I was planning on putting in a high performance torque converter already and was going to beef up the tranny or swap it out at the time of the engine build, depending on how wild I go with it. I think you read my post wrong, I said I would like to have 300hp at the rear tires, I'd like to get my torque up around 400 ft lbs if at all possible. I don't need this engine to rev over 4500 rpms and I want alot of my power made below or around 2500 rpms.

So does anyone know of any way to achieve this?

 

might try a 331 kit and some head work. thats my plans for this winter. 331 kit makes lots of torqe and the heads can free up 30+ hp (i have the dyno from VERY good sources)

you will need to convert to mass air or get a custom chip burned for you speed density, i would allso get a custom cam ground up.
