I am not brand loyal, I currently have a 2019 V10 class C I love. For years my daily driver was a 4.6 Crown Vic which was probably the best car I've ever owned. For the last 10 years my daily driver is a 5.3 Tahoe which has been fantastic, and one of my many Chevy LS.
Again, not brand loyal.
I remember when Ford came out with the "modular" V8/V10 their ads basically said how only a stupid cave man would stoop as low as to drive something as crappy as a prehistoric push rod engine. As I recall the ads compared the LS to the WWII jeep or a lawn mower due to the pushrods, while their modular had the super high-tech OHC (and in Lincoln, DOHC.) Here we are in 2020 and as I understand it the Ford 7.3 is a single cam pushrod motor. I'm sure its great. But its kind of funny. I can see why people are saying Ford copied the LS. The LS is an amazing engine I don't blame Ford for trying to duplicate its power/weight/cost ratio as well as its long life.
