Whatever gearset you run in the v6, I'll run in the v8 for the 1/4 mile. And the v8 is going to eat the v6. From experience. Because whatever RPM you turn in the v6, I can get from the v8. So whatever torque multiplication you get with your 4.10 (or whatever) rear end, I will also get in the v8. We are talking pure motor issues here. Horsepower is important. But so is torque, which is a different way of measuring horsepower. 8 cylinders will produce more torque, even at the same displacement. A V10 is better still. The problem with the turbo is lag. The V8 supplies torque _right now_. The I4 is going to die at low RPM, and waits until the turbo spools up to get moving. A good example is the old SVO mustang with an I4. Yes, it runs like the devil. Yes, a good 302 will suck the doors off of it. HP is about the same (220 each). My son and a friend used to prove this over and over. My son had the 302, his friend had a mint SVO. The SVO would run for an I4 (13.7 quarter miles.) The 302 ran 13.3's. But the main test is to start at rest and see what that turbo does. My son now has an SHO taurus with a v6, and yes, it runs great. Same horsepower as the 302 mustang (220). 1/4 mile time is 14.9. Car pulls hard at 4500-7000 RPM. The 302 pulled hard from 1000. As the old drag-racers proverb goes, "nothing beats cubic inches." And the best way to get more cubic inches is to get more pistons. :)
