ok, so i'm stoked about my 6.2 b/c i'm swapping in a 465 this week. got to drive one with that set up last weekend (tRustyk5's set up) and it blew me away how much power you can feel. really gives a nice seat-o-the-pants feel. i always see rene posting about how proper gearing will really liven up a 6.2, and damn is he ever right. you all need manuals and good deep gears. period.
that's all.
that's all.

..Shows how much I know about later trannys..I'm lucky I can spell SM465 correctly!..so what is it really?--a NV4500? NV5600??
..all I have to do is figure out how to bolt one up ,and how to hold the truck up after its in..I bet those weigh almost as much as the rest of the drivetrain,including the motor..
