I wish I have a 351 but I have a little 302.... I have MAC on my car and I LOVE THE SOUND!!!!!!!!!!!!!!!!!!!!!!!!! I just love the 5.0's cuz it doesn't matter what kind of headers, h-pipe, or mufflers you put on the car you can still tell that it is a 5.0 just by the sound.
I don't like flows cuz the are too muffled sounding and they are too common. I really like the MAC cuz not many people (at least in my area) have them and it has a mean grumping sound to it. I have the 3 chamber ones and you can still hear me down the street when I romp on it. With my body kit, I admit that sometimes that is even scares me
