I had a 2004 gt with a vortech v1 stock bottom end on 10 1/2 lbs of boost making 400/400 car lasted for ever I sold it and it still runs. I now have a 04 mach 1 with kooks longtubes and full exhaust thinking about getting a vortech v3 for her. What will the motor handle? Ive heard different numbers. I may even get new rods and pistons but im confortable with it making 500 if it can? Any input is welcome.
