engine question

I bought a 1985 Mercury with a 302 with 58,000 miles. I want to take the engine and put in my '66 Bronco. My question is it has first year fuel injection, Will I need different heads or just a regular manifold or should I try to use the F.I.? Thanks.

Heads should be the same ....
Toss up on which way to go on fuel delivery.
Whichever way you go, if you have the AOD transmission.
Be very careful!

First why a 66 bronco question in a 80-86 forum?

The 66 bronco would not have AOD and unless he used adapters he could not use the car trany.

Also know early broncos have a 6cly & v8 frames. So if you have a six in the bronco the v8 will not bolt in.
The frame mounts are part of the frame, welled on.

Can you install a v8 in place of a 6? Yes as I have done it 30+ years ago. Not hard from what I remember.

It was an engine question. I have a '84 F-150. but figured someone could answer the question. I have a set of V-8 mounts for an early Bronco and would use my stock 3-speed.

You have the rubber mounts to use?

That is fine but the rubber mounts will not hit the frame if the truck is a 6cly.
Just like 80 to 86 trucks have different frame mounts that bolt in the first Gen broncos do not bolt in it is part of the frame.

The 3 speed may be ok for driving but heavy off roading I would think twice.
I went with a C4 as the truck was built for off road racing.
If the truck has a v8 then frame mounts & trany is not a issue.

Sorry I can't help on the motor side other than make sure you get the right flywheel.
