1966 Coupe restomod
Hi everyone, I recently got my hands on a beautiful restomod 1966 Mustang. It has a 302 V8 bored engine. I drove it on the fwy in 4th gear, between 3000 and 4000 rpms for about 15-20 min. The car was rattling a bit, but I attributed it to the powerful V8 engine. Any harm that can come to the engine or other parts from doing that? (I'm too embarrassed to say why I did it, so dont ask). Just looking to see if I may have caused any damage. Thanks.
