Pretty sure a bullet would not stop the engine in my dually—a 454 gas version, which weighs about 550# on it’s own. All cast iron—NO aluminum!

I don't know what a "dually" is, but the best car I ever owned was a 1970 Monte Carlo SS454. That thing was a rocket ship. I sold it in 1979 because gas went up to 75c / gallon.

Actually, it probably would. Magnums have been used for this purpose by police since they were first available. They could break flathead Fords, and “modern” (post-1950’s) engines have better thin wall casting techniques. Some of those old engines were amazingly heavy (with cast-in oil pans) given their displacement.

You might think that an aluminum engine would be better, but the aluminum engine blocks are generally made with high silicon content, and are strong, but brittle.
