I do drive my truck. haha why do think i was asking what it'd do for my top speed? But, Ive had the RC 6speed...a 2004 with 4:10s....And 2QCs with 4:56s. These autos need a taller OD or another gear! And ya i want better fuel economy for when im not running her hard! But,untill I get this paid for,AND get another DD....I'm not running her at the track. Been there done that,In both of the other trucks. Hell,even blew one of them up on NOS! I will do some good mods later down the road and hope to even go STROKER and a set of TWINS....But till then....I wanna get better mileage. Right now Im completely content just driving her like a cruiser! Its funny all the people that try to get me to race and i just punch it long enough for them to punch it then let off of it and watch'em go! or just ignore them completely. Im happy just hearing those flowmasters sing to me!
