Chevrolet ZZ572/720R – 727 Horsepower
GM is known for selling some of the best racing crate engines drivers can buy. The ZZ572/720R is a relatively powerful engine that GM has been marketing for a while now. The 727 HP comes from the factory and offers some of the best performance numbers you can get out of a crate engine (via Jegs).
If you’ve ever wanted to build a muscle car, you can’t go wrong with this, one of the best V8 engines of all time. This engine is a powerhouse with a great design. Using an excellent design is only one part of a great engine design, and GM knows how to do it.
