First of all I'm new to the foram and very happy to have found this site! Can anyone help me figure this out? My K5 has a 350 sitting behind a stock drivetrain and axles. 3.73 gears. The truck has no power. I underderstand that the 35's will rob tons on power from my stock set up but I don't even have a passing gear. It's like there is something wrong with the trans kick down? Is this true or is the tires my problem? Thanks!
