"Nicks garage" shows what these engines can do for real. No Uncle Tony fantasy imagination nonsense. There are channels worth watching the thing is deciding if you want fiction or non fiction content. Nicks will show you LA 318 making 230-250- hp and he will show 340-360 making dern near 400 hp . It really is all about what you want to watch on YT. Uncle tony is for couch potatoes, Nicks is for guys actually building engines Just my $.02
