The motor came out of a 1973 Thunderbird, which at the time used leaded gas. Ford did not use this motor in trucks, they used a 390 or a 460. My motor will be rebuilt to accept unleaded gas, with all new internals. It will have fuel injection throttle body and will be turbo charged to help with towing. So why not use Gear Vendors? Sounds like it would improve gas mileage and towing regardless of motor use.
Actually Ford did use the 429 in trucks. They were used in Ford medium duties. The 370 and 429 were referred to by Ford as Lima engines. They replaced the Ford 361 and 391 in medium duties.
One of our farm trucks had a 370 Lima. I would of preferred the 429 Lima option back then, more power to move a load of grain.
Post edit:
I've been thinking about this post and in the case of light duty trucks, such as pickups you would be correct. the 429 was not used, but the 390 and 460 were.
I tend to think of trucks, more in terms of medium duty terms, than light duties. That comes from my grain farm experience.
