Done a million launches and burnouts on my bolted stockers. Been in for 2 and and half years and now working just fine at 1000hp. When my motor was out 4 months ago, the mounts were still in perfect shape.
The engine mounts held, it was the transmission mounts I was still trashing. I had talked to Eric merchant and he said in some cases he saw the bolts fixed the engine mounts but still allowed enough flex to wear out the transmission mount. I asked about different trans mounts and he said I wouldn't need them with good motor mounts. Put MA's on and the trans mount held till I flodded the truck.
Buy a set and sell one of them
I run both, the vibration is not bad. All of my boost pipes are v banded, the engine doesn't move around, I'm also running a poly Trans mount.
