It's taking a while. Almost decided to put another low mile 5.7 in but it's leaking at front and rear seals. Think I'm going to use the 6.0. Looks like the entire caddy exhaust should fit and work being same wheel base. Question what do I need to do to bolt motor to trans. 04 6.0l and 95 4l80. 5.7 is ready to lift out then I can see what converter is in it. I'm sure it's tighter than the ls wants but I didn't like the loose converter that was behind the 4l65. Should be fine with my idle speed just be a dog down low. The caddy has traction control if it was shut off it would blow all 4 tires up taking off so castrateing it with a tight converter might make it easier to drive in the snow without traction control. So flat flex plate or dished, spacer? I need to get what I need coming and a set of mounts. Got to measure and see if I can use the caddy radiator since it's big and new
