Rock Auto is selling the Volvo 164 motor mounts for as little as 2.49 each:

It'll be good to have a table of the different mounts available and their dimensions. I'll put one together when I get the chance.

Those RockAuto mounts are the same ones they list for the 4-cylinder 140 series of Volvo; I've never seen a heavy-duty mount for these WITHOUT the hexagonal plate.

Or you could just go solid, in alumin(i)um or plastic, and grind down as appropriate..

--Hmmm, Jeff, I don't recommend it, even for a race motor; or, should I say especially for a race motor (high performance). I've used both Delrin and solid aluminum on some race motors. When engine movement is restricted too much, particularly with a high output motor, the result can be a cracked bellhousing, or even the fifth gear section of the gearbox. The rubber engine mounts not only absorb vibration, but also yield enough to prevent driveline damage.

PS: you could say I learned this the hard way! :D

Thanks Jim, I wasn't considering solids, just saw these yesterday (I'd heard Miata mounts are even shorter than the Volvo) and thought I'd give these a mention; I don't think I'd like them on the Volvo either.

Just be careful of the oil pan sitting on the crossmember. On the 75 spider I got a few months ago with a 2L in it showed the pan and crossmember had been seriously rubbing on each other.

Thanks Carl I realized that would be the limit to dropping the motor on the crossmember; I just need the distributor to clear the hood on a '72 sport coupe; I haven't measured yet but I think I have more "headroom" than a spider.

Coupe should not be a problem, on some spiders guys have rotated the dizzy 180 degrees so the wire fingers point downward....looks odd but works to keep the plug wires from rubbing on the hood where they come out of the dizzy cap. On one of my spiders I just cut out a section of hood reinforcing that was interfering with the cap.
