I am currently inthe process of restoring a 1979 ford f-150 and am trying to decide which engine to rebuild for the truck, I have one of each. The 429 is from a 1969 thunderbird and the 460 is from a 1979 f-150. Thanks in advance

Mathematically, the answer is negative Ford 31...

But seriously, the answer is probably best decided on what you are doing with the truck. If you want to restore it as a work truck, the 460 makes a lot more torque, making it a better truck motor. Also, for authenticity, the 460 is a much better choice since it was an original option on the truck. (Although I would doubt that there's much value in spending the money for a faithful restoration on something as un-rare as a 79 F-150.)

If you are building this into some kind of cool street or tricked out show truck, either engine could be a good choice. The 460, these days, is easier to build into a monster-hp maker; Ford sells some pretty tricked out crate motors that make loads of power and even have warranties. The 429 would be more trick, but would probably cost quite a bit more to make equal power to the 460. Remember, though, the 429 was a late 60's car motor--they aren't efficient, and really aren't all that powerful in their stock configuration. If you want to use the truck as a truck, it's definitely the wrong choice. But as a tricked out street rod/truck, it would be way cool.

If money was no object, hey, how about building up that Ford V-10 truck motor into something really mean?!
