Same ones. Just took an 89 HO out of my 65 cv. Same mounts-- and will use them when I put the 289 back in.

No kidding? That's pretty cool The early '65 stud-type mounts set the motor a bit lower, great for hood clearance but not-so-good for header clearance. The late '65 thru '66 ear-type mounts put the motor higher, limiting hood clearance but provide more room underneath

Use the later late 65.66 and up mounting brackets. I've never used the early mounts in any early car. Always changed them to what I have now. The later ones will allow that fat original but usually use the Hi Po type a/cleaner

Since your car is a 66, I assume that you originally had the "ear" type mounts (not the 65 stud type). For the late 5.0 block in the Fastback, I used the Lakewood "Muscle Mounts" which are the 66 Mustang stock-type replacement mounts and are available from Summit or Jegs. They are more expensive than the typical 66 repros, but I assumed they were better; although I don't know that for a fact. They fit perfectly. I also purchased the sheet metal "mount heat shields" from one of the standard Mustang vendors to help deflect the exhaust heat away from the mounts.------------------ Bernie Frank 66 Fastback restomod project 85 GT (preserved) 82 GT (original)

The Lakewoods are better because they have built in torque limiting. Imagine if you will a strong bolt going through the mount with a nut loosely set on it. The mount works fine to isolate engine vibrations but when you stomp on it and the mount really stretches out, it can only go as far as the loose bolt and nut allow. This is torque limiting and its built into the Lakewood mounts. There is no limiting on aftermarket replacement mounts. Hi torque/hp engines tear up the aftermarket mounts.
