Mounts for Engine Swap?

[gerahead]

My project is a 71 Dart that was originally a 318. I am swapping in a 340. Can I use the 318 mounts for the 340 or are they different? Neither engine was in the car when I bought it, so I am assuming at this point that the mounts I have are for the 318. These are also the biscuit type lower mounts. Any pix of either type (if they are different) would be helpful to identify for sure what I have. Thanks. L8r

I think you need to change em out! Here is Schumacher's site! Click on 63-72 a-body on the left. Then it's the third one down. It says 273/318 and 340/360 brackets are not interchangeable.
Good Luck

If the 318 mount was a 4 bolt bracket, then yes you can use it with a spacer.

IF it's a 3 bolt bracket, you need to do something like this or find a 340 mount.

The modified mount to 340 size on the left strarted out like a 318 mount on the right.

crackedback,
Do I interpret the pix correctly that only one of the mounts is different? Thanks for the help. L8r

Drivers side is different, pass side should be the same as 318.
