Would it be safe to put a TSP Torquer V.3 Cam in my automatic almost full bolt-on 127,500 mile TA?

 

To end a debate before it starts, my advice is do a compression and leakdown test to establish the health of your motor. If everything within acceptable margins, then go for it.
And as usual, do bolt ons first or all together.
Also after so many miles, you would have to change lifters for sure.
