Oh I understand and I am a lot smarter than you think I am. The op has a Fast fuel injection set up on it now. It almost sounds like he is a young gun looking for a wow factor tunnel ram sticking out of the hood. If he was experienced and knowledgeable he wouldn't have asked "how big is too big" in the first place. Think about that before you talk him into it.
I'm not talking anyone into anything. He asked 1 question. "Will the 600's work or be too much and be a waste of time". I answered the question he asked. IF he would have asked what worked best, I'd had given him a different answer.
