I checked all of my records and couldn't find the motor mount part numbers. They are pretty common looking parts tho, perhaps you can visually match them up with something?




^Fpa headers. They fit perfectly with no issue. The ones above were installed in 2005, which should speak highly of the ceramic coating on FPA's.
I don't need them and would sell them, but I'm leaving in 2 hours to go offshore for 30+ days, so it would be rude for me to conduct business with no way of finishing the deal. I will have cell service, tho spotty for the whole month so if you need any other pictures of how a 429/460 fits in a Galaxie let me know. My car is a 63.5 but it's the same engine bay as your 64.
Biggest issue is retaining the stock hood. I used an Edelbrock Performer with a 2.75inch drop base air filter. A 1/4 inch spacer was all I could fit under the carburetor.
Dropping the engine any lower was a problem due to the stock oil pan:

Alan here on the FE forums mentioned an aftermarket oil pan that might have helped.
Otherwise the engine fits fairly decently:


Feel free to check out my photobucket album, I literally have a 1,000 photos of the Galaxie with a 429 in it.
As far as me selling anything, honestly I'd like to sell the whole engine as it really and truly is a great setup, headers most likely won't work with any future swap I'll dream up, so thy can go, but I'd prefer to deal with you privately on that. The only reason I pulled it was because I wanted an FE in the car. Also with the Gearvendors overdrive the driveline angles were excessive due to how high the engine sat. This problem was remedied with an FE.
Going from a 429 to an FE with these mounts lost about 1/2 and inch of driveshaft play btw, I don't know what your swap is, but just figured I'd throw that out as it might put you out of range.
Feel free to pm me with any other questions.
