Y'all are going ga-ga over nothing, because...

There is nothing special about a 429 "Thunderjet." It's not a HiPo, it's just a 429 with a 4V carburetor. The 2V version had no 'special' name.

The same engine was installed in 1968/71 Thunderbird's as std. equipment. Optional in: 1968/73 Galaxie/LTD/Mercury Marquis, 1972/73 Torino's & Mercury Montego's.

This engine is not that hard to find...considering how many cars used it.

IMO, it's not worth anywhere close to a grand. Here in LA LA Land, you can buy one in a pick-a-part yard for less than 200 bucks. You can buy a 460 4V for the same price.

Any 429 or 460 can be bolted into a 1965/66 F100/250 2WD using the 460 engine mounting parts from 1973/79 F100/350's.

But, this is not the case with a 1961/64, everything has to be fabricated (or a mounting kit bought from an aftermarket supplier-if there's one available).

What quality of workmanship was used to install this "Thunderjet" engine in the 1963, was it done correctly, or is it a "hash job?"
