The following is an attempt to get some of the basic information regarding originality for Thunderbirds into the hands of all who want it and to do it for free.

If there is information you wish me to put here or if you find mistakes I should correct, please email me Here.

1968-9 OEM 429 Thunderjet "Originality" Specs

John, I got these from an old Ford dealer detail manual that I picked up at a local flea market. It had a whole, detailed explanation of the "new for '68" 429/460 engines. The later blocks were painted regular Ford Blue, but it doesn't give a specific year. I'm still looking into it and see what I can find out, but it may be tough.

Exhaust Manifolds: cast, un-finned.

Master Cylinder: natural cast, w/ natural aluminum "double-hump" cover

Water pump: Blue as the engine is

Air Cleaner: Ford Dark Blue (NOTE: 1/2 arc "429 Thunderjet" foil decal (have pic), the earliest air cleaners had 2 snouts, all have one breather bung)
"429 Thunderjet" decal, I've actually seen two versions of this, one as described on your page and another that says "429 Thunderjet - 4V".

William Ora Mullen (BSCS/MSEE, CNE, COE, MCSE), has provided much of the above and I have added and modified some of it with the input from many of the visitors who have researched certain items.



For you who think I am the expert I want to warn you that I do not know everything about these cars. I am only posting what has already been determined by a large group of Thunderbird Enthusiast to be as close to original as we know it. Each club has different rules that they judge cars by at the shows and if you are competing in a show or intend to I highly recommend that you contact the club and get a copy of their judging rules so as to be able to know what you should do to be competitive in their event.

I also feel it is the clubs duty to provide these guidlines for its members so as to hold a fair judging for all participants. This has been my stand on this issue for many years and I feel it is one of the weakest areas of all the clubs for the '58 and up Thunderbirds.

To improve this situation I urge each of you to contact your clug hierarchy and bug them to increase their efforts in this area. As members and car owners the main thing we want in a club is information flow. Become active and get the info flowing.

That is what this website is all about. Please excuse any mistakes and help make the improvements with me.
