Default Fast Intake on a 6.0L Truck engine

What does it take to fit Fast 90 intake on 6.0L truck? It's head/cam/ bolt-ons.

Does the 03+ DBW TB fit on the Fast 90?

What size is the DBW TC.

Is it too bad to use stock truck intake with Head/cam in the range like 240/244. Cam should carry to 7000RPM.

You will need a 4 bolt throttle body and a wiring adapter. You will also need to relocate the idler pulley and possibly change the water pump.

There is a ton of info on this if you click the Performance Trucks tab on the top left of the page.

You should be careful with your cam choice since trucks are considerably heavier than F and Y bodies. Unless you have and steep gears and a converter, you might not like the way it drives on the street.

It's light weight RCSB and has 3.73 gears and will get a 3000+ TC.

I know that I will have to use F-body accessory. My concern is fitting the DBW TB on the fast intake.

Will be using truck rails/LS1 injectors using rail spacer and injectors harness adapter, so, no worry.

Does anybody sell 90mm DBW TB that will fit truck harness and work with Fast 90 intake?
