Just build the 4.6 with cams, forged internals, dish pistons, Manley h-beam rods, bolt-ons and a healthy shot of nitrous and you'll be in the 12s no problem. It's a more user-friendly approach but if you're looking for 9s or 10s in the 1/4 mile, you'll most likely never achieve that with a 16-valve. What are you looking to accomplish?
