If you are swapping from a 351M, 400, 351W or 302 to a 460 these will bolt directly to the perches that your truck, or bronco already have. They are for the year range 1974-1982. Additionally, they are built to the correct dimensions to allow you to use the full serpentine system and accessories of a stock EFI 460.
We have had countless customers utilize our 351M swap mounts as a universal motor mount. Why redesign the wheel if these work so well. We include (but do not weld) the perch bolt to give you more flexibility. Bolt them onto the engine then you can build your own frame perches from these out to the frame.
You can swap in a complete factory EFI 460 engine from a 1988-1997. If you already have a 460 that is still good you can take the heads and intake from the 88-97 and put them on any 460 engine. A 460 will even bolt up to the same bellhousing that a 351M or 400 will. Is it time to rebuild your 460 or Modified engine, or are you simply ready to ditch your carburetor and ignition system? Even if you’re just looking to add better fuel economy and power to your vehicle, an engine swap can be done in a day or two.
