I recently acquired a 429 and C-6 out of a '69 T-bird to fill the void in the engine compartment of my '67 F-100, 2wd. A 390 and 3 speed manual used to be there, but a previous owner decided he didn't like adding oil, and promptly burned the engine up. I have a few basic questions for anyone out there who can help me.
1. How big of a cam can I get away with before I have piston interference?
2. What headers and oil pan should I use to fit this car motor into my truck?
3. What was the motor rated at from the factory, keeping in mind it is out of a T-bird?
4. What is the compression ratio?
I can fabricate a trans x-member, and I am getting the PAW engine swap mounts. Thank you in advance for any help you can give me.
The CR on that engine depends on whether it is a 2V or 4V. The 4V is approximately 11:1 and 2V is 10.5:1. I would not worry about the cam having interferance with the pistons as lift is not as important as the profile. The stock pistons (existing cutouts) will handle a half inch lift and a little more. As for HP if I remember right it is something in the Mid 300s. Use the stock T-Bird oil pan on a 2WD. As for headers there many available, generally in the $300 to $400 range. You've got a lot of stump pulling power, are the headers worth while? If you are going to run the engine as is then you must use Hi Octane gas, retard the spark, and never try to pull heavy loads for a sustained period. Looked at the pistons from a 69 460 last night, the tops were melted and some had holes. Unless you use an Octane boost your engine could suffer the same.

I am doing the same swap into my truck. Here are some answers, as qouted from Ford Performance. The deck height is the same on the heads. The only difference between the 429 and 460 is the stroke and wrist pin height on the piston. The 429 in '69 was rated at 10.5:1 compression for both the 2V and 4V motors. As for HP, the 2V has 320hp, the 4V has 360hp, and the 4V-Boss has 375hp. The same year 460 had 365hp. These are stock unbored numbers. Remember, these numbers are also said to be conservative estimates! As for the cam, speak with some one at the "cam dealer" to ascertain which profile would be best for you. This varies according to your driving style and needs.Last but not least, headers. L&L in Rowlett, TX makes headers for this swap. I have heard that there are clearance issues with any other than the specialty set up. I don't know, as I haven't made it that far with my project truck. Good Luck!
