Thanks Ace! I haven't updated the build thread in a while because I've been sidetracked by cold weather. The 5.3 engine arrived last week, but I probably won't get much done on the installation until Spring. In the meantime, I'll use whatever warm days we get to continue the rust repair in the floorboards. I'd like to get the interior back together before we dig into the engine and trans install.The Muscle rods conversion will make it easy. I am finishing up an LS3 6L80e build now and if I have learned anything it is buy parts designed to work together. Buying all the "good stuff" from the various manufacturer's does not mean they are going to all work and fit well with one another. Here is a pic of mine and you can see how well it all fit, even the much bigger trans.
