Motor mount question

I dont plan on doing any hard launching but then again I get a brain fart once in a while.
I think Ill box the biscuit. But still looking for
correct 340 mount. I just like to have things like they should be.
I kept ripping the mounts in my 69 Dart. So I went to Moroso solid mounts. Way to rough for me. So I wound up with the Poly Locs. Much improved.
