[Fot] Intake Manifold Crossover

[Bill Babcock]

Damn. I washed Peyote prior to sticking it into the trailer and was  
running the motor to dry it off when I noticed the water pump inlet  
hose sucking flat. As I stood and stared at that I noticed the motor  
mount looked weird. Yup, broken.

I know this is a topic we've covered before, but has anyone found a  
better motor mount or come up with some rational modifications. I  
break at least one per year now that I've gone back to the stock  
rubber mounts (I was using home made solid mounts, but they do bad  
things to the bellhousing).  I'm thinking about drilling through the  
mount and countersinking a couple of bolts with loose nuts, but  
that's going to take a lot of fiddling to get right.
