Engine swap

Hey guys i'm knew to the forum, but I have had a ford in my driveway since I was a kid. Here's a question I have, I just bought a 1986 f150 with the efi 302 engine. I'd rather have a carburated version of the 302 in this truck. I want to change the engine but I do not want to hack up the wiring to chage to a carb engine. What are my cheapest options. How have any of you done this swap. Any help would be great.

Thanks,
OFK

Go to autozone and get a ignition module for a 85 Mustang with a automatic as well as the distributor and coil.

Find a duraspark II wiring diagram online, and wire it up.

You will also need a new fuel pump as well as a throttle cable.

If I were you, I would leave the EFI alone. EFI driveability is 1000X better than a carb.

You will have to hack the wiring, no way around it. Your best solution is to sell this truck and buy a older one with a carb system already on it.

Most engines are. My 300 is the exception, but only because you can't build it as cheaply as a carb'd one. Still, I have 20 more horse than a basic carb'd 300 and never have to worry about the timing or anything. So.. EFI rocks.

Boy, I wish. How come those headers were getting so hot, so fast? I understand the hotter the exhaust gasses the more power you make via the turbo, but I think with headers getting that hot it wouldn't be good for a daily driver?

Edit: Hey hitman, you have any more pictures of your '85? I want to see it with the wide rims. What kind of condition is the truck in? You should sell it to me. =D

A turbo puts a huge restriction in the exhaust path, which is why turbocharged engines do not need to take backpressure into consideration when building an exhaust. It creates its own. Plus, with all the gasses being compressed at this restriction, it creates alot of pressure, which creates heat. Lots of it.

I've had my eclipse turbo and manifold glow on a number of occasions, it just comes with the territory of making alot of power. Doesn't really have any effect on whether or not it's good for a DD. Just have to make sure temps stay low enough that you don't start melting things. I've vented my hood to help alleviate all the excess heat created by the turbo. Helps when you want to open the hood to look at something and not bake.

At what point does things like belts and hoses start to melt? Man, that's a lot of heat!
