Anybody running a ZZ4 crate motor in thier rig? If so, how do you like it? I never really considered one(was looking for more power) but I know a guy selling one almost brand new for $2500. It's not the power level I was looking for (400+hp,400+tq) but it's definitely a better start to build up later than my Goodwrench 350. What do you guys think?
