Is this an aluminum CSX? If so it should be similar to the install on a Kirkham. Search the site for the Kirkham assembly manual. On my car I took off the hood, the seats, the trans tunnel ( and drilled out the rivets and took out the panels above the tunnel). Remember to take out the
oil seperator tank if you have one. Put the headers in through the side pipe cutouts before engine install. It can be done after on the Kirkham, but it is a PIA. I put the engine in with the trans as one piece without any problems. Radiator was in place. I actually used my 2 post car lift to raise the engine for the install, my cherry picker did not have enough reach. I just took off the pads on the front 2 arms and used a piece of square tubing to connect the arms. An engine leveler is helpful. I had 2 good friends help me with the install, and it took about 10 minutes to slide it in. One friend in the front watching the clearance on the nose, and one in the car guiding in the trans. It went in pretty easily.
