[LS short box]

Since you have a a 24 tooth crank it might be easier to run a DBC throttle body instead of a DBW? I've run the 2002 Camaro throttle body on a number LS swaps. No need for a BCM. Don't know if that works on a truck intake. I've always used an LS6 intake on my early LS swaps. My 98 Wrangler with a 2002 Camaro LS/4L60E swap charges just fine even when using the snow plow. 14 years on the swap zero issues. Howell LS harness.
Same for my 68 C10 LS6 /4L60E swap.
