ok, i plan on racing a lot this year on my new motor, i only have stage 2 cam, 11-1 piston, HMF pipe, UNi Filter no lid, Anywho At the end of this year i plan on an entire new motor for 2006 nationals ( 4-stroke c class, then B)

Baldwin is a couple hours from here, but who do you guys reccomend to build me a reliable motor that will stay with 450's. I have a nice suspension setup ( TCS all around) But now im gonna need the motor to be competitive at nationals. How much horsepower do you estimate i have now, and then how much could i get with a 440?
After 06 i will purchase a 450, or w/e is out then lol.
