Iv installed the 351w in my 64 wagon. I used the stock 289 motor mounts. I will see if I have any pictures of the mounts. I trimmed the shock towers back. I cut out just enough so a flat plate wouldnt hit the coil spring. You can leave the control arms exposed. I might have pictures of this as well.
I ran a c-4 behind the 351w with no problems. Used the same rear mount if Im not mistaken.
