Joe & all, way back when we were racing the fuel car we had only a motor
plate bolted to the frame. The front mounts were bolted to the block and just
rested on the top rails. Has this theory been updated since the 70's?

Bill,
The topic of block stressing is an interesting one. I had a customer who ran
solid side mounts and a mid plate on his blown, injected, nitrous squirted
small
block 32 street-driven roadster. He kept blowing head gaskets and torching
the
blocks and heads so I installed a front plate and he never had another
problem. I
really don't know if it made a difference but I got credit for solving a
reoccurring and expensive problem.
There isn't a competition car in drag racing with anything but front and mid
mounts and I have never heard of motors failing do to stress from
mountings...just driver abuse!!! Also, most drag stuff use lateral limit links
to
keep the motor/trans from moving fore and aft if the mid plate isn't securely
bolted into the chassis. In dragracing, this link system is good for a tenth
or
so in e.t. on some cars.
Of course, horsepower comes into play when considering how to mount a
motor/trans
package. More power---stronger mounting required!
Hey Jerry,
Happy Mounting...hope you are not too confused!!!
