    6.0L in to a 91 Chevy silverado 2500 Light Duty

    Im new to the form page. I have a 91 chevy 2500 light duty EXT Cab 2WD. It curently has a 5.7L TBI 350. I want to swap it out for a 6.0L iron block flat top pistions. The trans is a 700R4. Just want to know where I can buy engine mounts, fuel pump, tranmission adater if needed. Id use new steel braded fuel lines. Also can i us the stock brake master cylinder and booster? Or do i have to use a hydroboost Brake system If anybody can help that would be awesome. Iv been wanting to build a LS engine for some time now...

    Engine mounts- GO swith dirty dingo adjustable mounts.
    Fuel Pump- http://www.summitracing.com/parts/EDL-3581/ this is what i bought and this will connect to your factory harness. The pump even says walbro on it even though edelbrock is selling it.
    You can use your stock master cylinder and booster. My 6.0 had hydroboost on it, all i did was block off the line with a cap.
