The motor is a 350,new. Transmission is a turbo 350, tires,will be changed. Not sure of current ratio.no sure of the rear and it's all under construction.

What transmission? What engine? How tall is your your tire? What's your current ratio? Which rear end is in it? Also know the speedo will need recalibration.
