    With some free time, I'm building a 360 for my '80 F body. Presently its a 318. Has the factory motor mounts. The 360 should be making abot 450 HP. Looked at Rock auto for new mounts, not just the insulators. They don't show any difference between a 318 and 360. I thought the drivers side mount is different. Whose right?

    I don't think you can get the 360 motor mount new anymore. When i needed one any that came in were the 318 style.
    It's no big deal to use a 318 one, personally I'd do that over using an NOS one with who knows how many decades old rubber.

    I ran them on a 360 for years. If you don't want to spend $160 on mounts though then as said, you can make the driver's 318 mount work by shimming it with washers.

    I feel the opposite on the rubber part of the mount. The quality of rubber from India and China is poor at best.

    It's a gamble I'd take. Yeah new rubber is junk. Boots on Moog suspension parts prove that. But old rubber can go bad pretty quickly once the stress of being used is thrown at it the same way old tires can start cracking or wear strange even tho they've never been used.
    I'm running a chinese engine mount and transmission mount, neither have failed yet. Can't same the same for NOS transmission mount. Then again I also have a poly one ready to go in.
