hi guys, i have a 2004 Roush Stage 1 Mustang automatic with a V6 and I was thinking about putting in a V8 crate engine with around 370HP. I have not bought the engine yet(do you know of a good web site to look at?) Anyway I was wondering if i have to put in a better transmission (i think i have the T-5) and/or a better rear end. Also ive herd that there are a lot of other parts that i am going to need that do not come with the crate engine... is this true? if so what parts? Anything else you know about this swap would be helpful. THANKS
