    If you have the right 2004r builder like Husek or Janis the 2004r is a fantastic trans, i run 800 lb/TQ behind one in a heavy Turbo Buick.
    Only a hand full can build it right.

    I have rebuilt the suspension all the way around. Everything blasted and powder coated. New control arm bushings, shocks and springs and links. No rear swaybar. It’s lowered 1.5 inches (I liked the sag look of those tired springs) With qa1 shocks. It rides really well.

    I have over 600 on mine with a lock up on a switch. The car runs 11.40s at full weight. To be fair it has only been to the track twice just to get a number.
    If I thought I could have used the 4l80 without tunnel mods I probably would have butwas told i couldn so i didn' even try.

    Yup. Snowballs are easy to make:). Also much easier to get to the fuel tank rubber lines w/the rear out & replace the brake line while doing the body mounts.

    One of these might be could be. Yours was intended for the next batch,but I haven’t heard from on of the people that I set one of these aside for. I did weld tabs on it for disc brake hose brackets,but you can still run drum brakes and all the stock stuff without them being in the way.

    Any recommendations on a good body mount kit?

    I prefer to run urethane body mounts,but someone people think it makes for a harsher/noisier ride. But hey,it’s better than solid steel.
