I am looking for a few suggestions on what I should do to my 400 to help add some extra power, besides running alky. Everything I have done to it is in my sig. below.
Thanks!

 

Hey 16, how is the season going? I run again here in a couple of weeks. Just finished with the oil block off and the starter block off. Put on a new silencer from RCR. Dropping as much weight as I can. As far as you going faster, 5 seconds is fast. Maybe a rocket engine LOL

 

I won second place last weekend, but I would like to get it in the 4.99-5.00 range instead of 5.1. I know it doesn't sound like much but it can mean a whole lot.
