I think _J_'s v6 would still rape a stock ford GT motor'd mustang...He didn't say ford mustang GT motor....He just said ford GT motor...And i'm pretty sure a ford GT motor will completely rape any mustang :lol

Your engine definitely won't hold up to any kind of forced induction which in the long run will cost you unexpected labor/repair costs
Do it right and throw in a bigger forged motor....then you MIGHT need boost
