I have had A BDR with a coyote motor with 492HP and a T56 transmission for approx 2 1/2 years now. Never had a problem with the windshield, motormounts or the differential. I have had a lot of fun with it so far.
Don't know who has been giving you false information. Fake News problably.
Maybe you should buy a Motorhome and wrap it and make it look like a Cobra.
