Hey guys figure yall could lead me in the right direction. I have a 03 suburban z71 with the 5.3 with a 12 inch lift 38 inch tires on 20 inch wheels i have the magna flow free flow cats dual flowmaster exhaust 456 gears k@n cold air intake and i just bought a radix 112 to put on it and it comes with the 3.2 pulley and i am going to get it tuned after the install of the supercharger. I know i will need to build my transmission so what would you guys do to build my 4l60e for everyday driving and towing my boat or what upgraded one would yall put in it? seen a bunch of people running the flt trans but not sure what would be the best bang for the buck or what other companies are good. Thanks in advance.
