I will be dyno testing a new pump gas combo that I expect to make over 650HP with. I will post some numbers and some build up pic's if you guy's want! I already posted a short block pic in my gallery!
 
I turned over one or two more stones and found a bunch of torque plus now I'm making my peak HP exactly where I like to set my max prop RPM. My 450HP is now making over 500HP and my 550HP is making over 600HP!
 
I have been promised it will be up within 4 day's! It has been a huge pain in the but and I can't wait until I'm done with it!
