You should PM TParker, he has a ZX3 not an SVT but, I have seen him run mid to low 13's. He has everything done and I mean everything. Coilovers,race headers, FS stealth exhause kit, radical street cam set up, cam gears, chip, drag radials, car at 2250 lbs with him in it. You might have a lot of work still to hit 13's, not trying to discourage you, I've read your mod list and I know his is all I'm saying.
