||The Bronco was abandoned at my girlfriend (now wife's) father's ranch since it didn't pass California emissions (and wouldn't start) with the promise of ''I'll pick it up next week.'' Four years later, it hadn't moved.
He gave it to me if I could get it running, so I did some work and drove it 700 miles home to Idaho. My first Ford, my first truck, and my first 4 wheel drive.
Since then, I've put 45,000 miles on it, rebuild the entire suspension, brakes, transmission, drive train, and have turned the slouch old tired 300 into a powerful and fun torque monster.
No idea how many miles are on it. Pulled the original engine and it had been rebuilt once already and had since then worn out past 60 over. 400,000? 600,000?

Here's a shot of the mostly stock engine bay. The only thing in this picture that isn't completely stock is the EFI 300 exhaust manifolds. It's time to dig in.

These pre-shaped pieces showed up in the mail. The fact that the tailpipe was made specifically for the Bronco and the Y-pipe for the EFI manifolds on a straight six really saved me time and money.

The intake removed giving a clear shot of the dual exhaust manifolds of the EFI 300. MUCH better than the restrictive six-to-one stock 1bbl exhaust manifold. I thought about painting those when I put them in but I didn't want the rest of the engin...

The intake with the heated spacer. This particular spacer is designed to run coolant underneath the carb to prevent it from icing, especially in the winter.

Everything's in place, the lines are hooked up, and it's ready to go!

The custom made accelerator bracket. Cost about $6 for the steel.

Putting on the last, and final touch after we tuned it. It is time for a test drive.
