I think the "raised engine mounts" that you're looking for are the '66 style V8 engine mounts, which you should already have if your car is a factory '66 V8 car. The V8 engine mounts for '65 Mustangs were a different design and made the engine sit a little lower. I've heard arguments both ways for the 351w swap into the early cars. Some say use '66 mounts to raise the engine up and gain clearance at the shock towers. Some say use the '65 style mounts to lower the engine to gain more hood clearance. The '65 style mount has a reputation for breaking in performance applications, but there is simple modification that I think is outlined on Mustang Plus's website to fix that problem if you decided to go that route.
I have a 351w in my '65 and I'm using the '66 style mount to make the engine sit higher. I have the headman shorty swap headers. I personally don't know how people use the '65 style mount in this application without the headers rubbing the shock towers. I wish I could drop mine a little and gain some hood clearance, but I don't think I can without my headers rubbing the shock towers. I have an Edelbrock Performer intake (which has a pretty low profile), a Holley street avenger carb with 1/4" spacer to insulate it from the intake, and a Hi-po style breather with 2" element. With that setup hood clearance is tight. I'd like to change to a performer RPM or a stealth intake, but I don't think their higher profile would fit under my stock hood.
There are some aftermarket motor mounts available, but I can't comment on them as I don't have any experience with them. Ron Morris makes a set and so does Total Control Products.
I hope this sheds some light on the motor mount issue.
