At what HP/TQ range should a person consider adding a torque limiter strap? What other variables should be considered?

Stock mounts can fail on less than high-perf applications. If you're making any kind of power at all (say from around 300hp up) I'd at least go with interlocking mounts (poly or otherwise). Better yet are solid mounts (
), which also serve to stiffen the front of the chassis to some degree. Same part number fits SB or BB in C3's.
IMHO, a strap is a crutch out of Bubba's shop manual (yeah, I've done it too), even tho they have been accepted by many sanctioning bodies thru the years. If you're making enough power that solid mounts won't do, you really need motor plates. Just my $.02...

I remember a recall back when 69 Nova SS big block. The dealer installed a cable around the exhaust manifold to the frame. At the time I thought that was kinda BuBa fix. But thats what they did.

I found this at Eckler's (part # 27500)
it says two are needed but I only ordered one for the driver's side. Will one work or do I really need a pair of them?

The first time I saw their recall solution, I was sure I had found the origin of "Bubba"...
The good news was that GM shortly after this (70-71 timeframe) came out with the interlocking motor mounts shown here for little more than the old ones.
shmoky... the drivers side motor mount sees the majority of torque as the engine tries to separate the motor mount so this should work, but I must tell you, I would replace both of them.
Back in the day, a lot of folks would simply drill a hole through the center of the motor mount and install a bolt with a nylock nut. (Don't torque it, just snug it up.) This would relieve most of the torque stress on the mount that would eventually separate it, but didn't interfere with the vibration dampening qualities of having the rubber mount.
Good luck... GUSTO

Have fun and if you happen to video tape a clip of it running shoot it to me, I can't wait to hear that monster rumble.
