The Hooker header mounts from Speedway about $79.00. Don't be confused they are available in several set back dimensions, I used the Stock location ones and they worked great, either way you have to deal with tranny cross member location and have a correct drive-shaft built. Nice Truck by the way. To use an LS6 intake you sacrifice bottom end torque and move torque and HP higher up the RPM range. Not a particularly good application in a truck unless you expect to be up around 5500 RPMs a lot, does Look better though.
