my buddy is telling me I should get an 850 w/mechanical secondaries and I'm thinking that's kind of big. I just started my car for the first time today and that thing was super loud. It's a street car. I want it to run as strong as I can get it. is an 850 too big. You guys probally already know what I'm runnin you always help out a lot. Thanks I'm just a rookie this is the first v8 I've ever really built up. Thanks budget budget budget
