[QUOTE="Jroc, post: 11273173, member: 51847"] I depends on your application. In a car yes, and for all out HP yes. Believe me I have a Terminator.(even though I wrecked it) I a truck I prefer a health 2v as it's best power is down low and makes a ton of low end torque that the 4v's don't which really help get things motivated and it's good for what I use it for which is towing/hauling, and IMO a health 2v sounds better than a health 4v.(thats not to say a 4v mod isn't a great sounding motor) Trust me you can build a badass 2v even though it seems more of them are 4.6 based motors as opposed to 5.4 based motors for some reason. Check on Modular Powerhouses forum, and you'll see plenty of 281/284 ci 2v motors that straight put the positive displacement blower 4v motors to shame. The threary behind why the 2v Mods do so well against the 4v mods with TS blowers is that while a N/A, turbo, Centrifugul blower, or N2O setup's prefer overall flow a positive displacement blower really like exhaust velocities as much as overall flow.
