What's the part number for the Energy Suspension Mounts? Are they locking?

Ths rubber mounts did not make it through 3 hard passes. Moroso solids seem bullet proof but the vibration has me wrenching like it was an old Harley.

Plus, i've heard the poly mounts will melt.
P.S. I really like your car. It has that bad azz look! With a motor to back it up.

turtlevette,
It's not at all bad in the driving experience. I just have to keep after the small nuts and bolts like the float bowls, carb linkage and stuff like that. It's not a big deal, just something you have to be mindful of. I wouln't change.
I'm like you. I like edgy, loud and fast.
No knock on Harleys, but the old one's were notorious for vibrating loose.
Thanks for the compliment. If I live another 25 years, I might get it finished.

I can't remember where it was, but I remember reading somewhere that solid mounts aren't recommended - even for drag racing. Seems that they can create internal stresses in the engine when under load. Anyone else hear of this?

Since you have solids, you know what I'm talking about. Its a good thing sittin at a stop light with the car rockin from the engine hittin hard. Luckily I don't have a carb. One other thing to think about is by solid mounting, you make the frame a little stiffer. Just a thought. Kid Vette, if you engine is balanced, you shouldn't have a problem.

I'd suggest the energy susp. poly mounts also, I've had no problems with them. I went through 2 rubber mounts in one summer before I made the switch.
Does anyone know if the aforementioned melting problem with poly mounts is true?

I would rather have a solid foundation than having the motor twisting and flexing against the rest of the drive train. The more stable the motor is the less stress. As far as vibration, it's going to be in the motor whether it's transmitted to the frame or not.
502RamjetVette,
Amen to that!

Re: Solid, rubber or poly engine mounts?? (jpatrick636)
some racers recommended solid engine mounts considering that I'm going to run a transbrake which requires maximum strength on the engine mounts..

Energy Suspension Poly mounts here too. Went with them when I put in the new engine from stock mounts. I really didn't notice any ill side effects.

I found the reference that I was thinking of. Not saying its right or wrong. This is from "Chevy Performance" by John Mechelsen, page 17.
"Solid mounts have been popular in drag racing, but they create torque stress in the cylinder walls next to the motor mounts. A better plan is to use cushioned mounts and restrict engine movement with a torque strap at the front of the motor."
What do you guys think?
