I read on the 429 Mustang and Cougar Mega site that the engine bracket that mounts to the frame is a little bit taller then one for a 351c, but they don't list any dimensions. Form the picture it looks to be about a 1/2" or 3/4" difference. It states "The top surface of the 351 frame mount is just a little bit taller than the 429 frame mount. This taller height will prevent the 429 insulator from dropping down far enough to properly line up with the thru-bolt holes". I have an original 429 car that came with a 351c. Now I am getting ready to put a 429 engine in it. I have the motor mounts that came with the car, but I don't know if they are 351c or 429. Can someone measure the height of their mount either a 351c or a 429. That way I would know what I have. thanks
