I looked under the hood for the first time in a long time, trying to figure out where my 351W would mount. It seems that there are 2 holes on either side of the engine crossmember, a small hole down on the crossmember and a larger further up. Does the 351W drop into the smaller holes or the larger ones?

 

2 holes on either side, long bolt goes through mount, crossmember, and back through mount. Check your mounts for fitment before you put on motor. Both sides need check, place done on frame and run bolt in it. Good Luck
