I have a 2003 silverado v6 that i put in a 2005 5.3 V8. The truck has a volant CAI with the ram air scoop, borla muffler, and a hypertech programmer. I was wondering what could this truck make in the 1/4? I plan on adding 4.10 gears and positraction later. Also, it is a 2wd regular cab, short bed, stepside.
