What fuel pump to run on a mostly stock motor?

I'd agree w/ Rick.....go w/ the biggest you can/want right from the start (when it comes to the FP that is) so you're not swapping it out 2-3 x's later on. Either 190 or 255 would be the right choices.....depends how far you think you'll be getting into this game!
