318 - 340 swap

Kinda funny i had to buy a 318 mount since my 340 did not fit my X block. I always have need for the opsite. Took me while to find the 340 one i packed away.
If I would have not located it would have just used a spacer over a stack of washers since i am.putting a 340 back in.
Maybe it's just me but rather have one nice spacer over a stack of washers
