im looking at a 1/2 inch bolt coarse thread, length to be determined.

Sirrotica, lol, yes, my curse. i always try to make things juuuust a little bit better than before.

It drives my wife crazy whether we are planning something, making dinner together or remodeling the house.

so that is why i see that a chain bolted to the frame has worked for countless people but i just want to take it to the next level. it seems easy enough to incorporate a urethane bushing and as i mentioned earlier i feel that it will still take out the shock when the chain runs out of slack as im banging through the gears.

here id a pic of the bracket. this will be the view if looking at the back of the drivers side head from the driver seat. the chain will be welded to the 1/2 bolt with a nylon locking nut on top. the chain will be bolted to a bracket welded to the frame. with the nylon locking nut, it will make it adjustable. i also plan to weld in a shallow bucket top and bottom to keep the bushing centered.

over engineered...yes..better than a chain bolted to a motor? time will tell.

Looks good, Vic!
That's exactly what I was describing.

I think we are talking about different things. im using a 1/2 bolt for my custom mount seen in the pic..

Like this??

I welded a 5/16" bolt to the underside of the tab. Without the bolt, I dont see how the tab does anything?

More importantly, will this work?

I don't think the tab does anything, unless the rubber fails. Then it is a safety.

Couple of thoughts. For the dragstrip, I would prefer the turnbuckle because of its ability to prevent engine movement - the less stuff squirming around, the better. On the street, I would go with the chain (or preferably cable) and maintain about a 1/4" slack to prevent transmission of engine vibration to the frame, to the steering shaft, and finally to the steering wheel. This will allow the engine mount to do its job of isolating vibration, and also put a specific limit on engine lift. Only time you want the chain tight is under acceleration. If I felt any vibration at idle or normal cruise, then I would add just a bit more slack.
