Early Bronc
I had a '66' half-cab. I took her through several changes in the years I owned her. The original drive train was a 170ci six and a three spd column shift. I transplanted a 289, with a toploader 4 speed. Next mod was to drop the suspension mounts to give it a 3" lift. then I installed a T-18 fourspeed. Traded the 289 for a 351 Windsor, this was perhaps the best combination I had in the Bronc. I then decided to build up a high winding 289. This combination was fun to drive, but it wheeled much better with the 351.
I finally sold it to make a down payment on my first house. In retrospect, I wish I still had the Bronc. Waaayy less maintenance on it than the house-and much more fun, I might add. In all this thrash I did learn quite a bit about the early Broncs, and I still have many contacts, so if I can help you out, let me know.
