Ive searched about the SRT valvebodys and didn't come up with much information. I want to know how hard the install is. I consider myself pretty mechanically inclined having built a motor and rebuilt a t-5 transmission with help from friends. But I think auto's are a little more complicated than manuals. Besides harder shifts, what can I expect out of this upgrade? Also, Ive seen people say it's 350.00, but the SRT site advertises it for 500.00.
