Paul,
I've just gotta ask - why haven't Tracy's rubber mounts melted?

Ken Powell


You got me.

I checked a picture in his book and the rubber bushings are
no where near his engine. He used the dynafocal mount.

I should have remembered that!!!  If I were going to use this mounting
scheme I think I would throw a couple of the Barry mounts into an oven
and test them out (after all, they only cost about $6.00).  What would
be a reasonable max oil pan oil temp - maybe 240 degrees F.?

The new rubber Barry is now using is Neoprene and it is rated at 93 C
or 200 F. Page 20 Barry Catlog 4th edition.
