    Re: 429 Engine

    I used to own a 64 deville with the 429. Mine was kept stock so im not sure about performance parts. But if you need parts, I used to use www.caddydaddy.com. They are a bit pricey on some things, but they usually have hard to find parts.

    I have a 1964 Fleetwood with the 429. When I was rebuilding it, I found "USA Parts Supply Ltd to be a good source. They can be reached at 703.335.1935, or www.usapartssupply.com. Stock parts only.

    Re: 429 Engine

    I just replaced the exhaust on my 65 coupe de ville, did it myself, it had single exhaust . I cut the pipes just after the manifolds on both sides got some 2" pipe and a couple of cherry bombs, exited the pipes just after the doors on both sides, and presto ! cool dual exhaust, sounds great , looks great , performs great, if your inclined and have acess too a set of torches..

    Run a supercharger setup for a 460 c.i.d. Ford on your 429. An adapter kit available to execute this project.

    Re: 429 Engine

    I ran 2 1/2 inch duals on mine back when I built the engine on the old 65. If youre going to get into modding this motor, know that it costs a friggin fortune to have custom parts made. Most obvious mod setup is a 650 carb with dual exhuast and a K&N. If you want more, it gets a little nuts.
