I have a 2002 gt mustang. Just hit 80,000 and its just about paid off. I only have 2,000 right now, but I save 500 a month so im wanting to start a lil project. I want around 400 hp for now..I was hoping I could get that with around $4,000 with me doing all of the work. I want it to be pure motor, I was thinking a 347 stroker ? But what block should I use ? I was told the 4.6 blocks that are in these cars can't handle over 400 hp? Eventually I wana be able to put twin turbo's on it to get around 700-800hp. So I need a pretty good block. What do you guys think I should do ?
