Well I have done all the body work I want to my car so now it is time for motor work. I personally dont like the basic 4.6 non pi. Doesnt seem to be strong at all. I want opinions from you guys if I should build out a 2 valve or get a 98 cobra 4 valve motor. My dad mentioned that he thought it would be kewl to get a 3 valve out of an 06 or something. But I am just trying to figure out what has the most potential and what not. Any comments would be great.
