Engines that will fit. 289 302 351w 351c 429  460 This writeup is meant as an overview for the '74-'80 models, i have not done a '71-'73 conversion so i'm not real sure what will work in those.
I'm sure you can get any engine to fit, given the time and enough money, but these are the most common ones. This article deals with the Windsor family of engines 289-302-351w The Clevland and 385 series of engines (429-460) have even less parts available for the swap and in MY opinion require a great deal of custom fabrication and reconstruction ....especially with the 429-460 engines. Â
It's maybe about time i did this thread. I get a good number of emails, and private messages about my set up, what i used and how to do it. This thread will take me a day or three to complete so bear with me and i will finish it as i have the time, along with a how to on EFI conversion for a V8. The parts i used are just that....it does not mean you can't substitute for something along the way ....if it works...do it! First off, a V8 powered Pinto is not meant to be a corner carver! It will not handle like its on rails....and would be suited for straight line acceleration (drag racing) and regular street cruising, so think about what you want your Pinto to do before you take the plunge.
Motor mounts- i used part number left-D7ZA-6B032-AA
                        right-D72A-6038-AA
They are from a '77 Mustang II 302, and they are pricey if you can find them at all. You also need the frame mounts from the Mustang II OR you can use the Pinto 4 banger ones and modify the left one by relocating it back 1 full inch from centre of hole to centre. A motor plate or engine plate can be used, however, they have no rubber mounts and will let the engine vibrations transmit through the car.
