Thats whats on there now, not running as smooth on the 350 as the 305. I think Vile is going to do a couple final adjustments. Actually it idles and runs very smooth, starts are a little rough and still a pop when i floor it. But no pop when i floor it from a dead stop. And,,,shouldnt i be able to roast the tires? Feels a little boggy. IMO. But i am not complaining, we'll see...
