I agree with most you said EXCEPT the last part. I'd be pretty confident in saying that 5.0 mustangs are the CHEAPEST to get to 500hp. Buy you a fox body for $1500 (they can be had cheaper) put about $5000-6000 dollars in it, and you'll be at 500rwhp. Now yes, if you want to spend some big money, you can do that on a mustang too, but there is always the cheap rout.Originally Posted by Big Rick
