Going to be an awesome build. If you keep showing this many pics of the entire build this thread will be incredible. That SS is going to be unbeatable!

our trucks should be very similar erik. except the drivetrain. which i think will be a challenge as well for me.

the transmission had always been the limitation on the awd trucks. i think with a built 80e the other weak spots will show. im just hoping the front diff can hold because there isnt much i can do to add stregnth there.

my goals are a bit high but hopefully attainable, 1000awhp and 10's with ease. low 10's would be awesome and maybe for ***** and giggles ill put it on a diet and see what happens.
