First post on the site. Bought a '03 on Valentine's Day (she was with me too!). Came with 16 gauge double barrels on it. I have added the 28T, K&N filter, topless with relocated IAT sensor, and the MoCo flash. Love the power but wish for a taller 5th gear. I have looked around the site but have not found any discussion on a six speed tranny or a taller fifth gear. Any info out there? Turns 5k at 80 mph.
