hey tommy, i'm doing a 5.3 swap also and made adapter plates too. i just picked up a set of manifolds off a trailblazer ss that fit perfectly but they have no egr. also i'm using a 4 speed but i see your using the auto. are you setting the frame level and setting the motor level? you may want to mock something up to check your clearance for the driveshaft. looks awesome though man, good luck. if you run into any problems hit me up i may be able to help. oh and i would definitely find another harness, if you solder all those connections it almost guarantees something won't work properly due to increased resistance or voltage drop. also you may want to check out ls1tech.com theres some good info and parts over there. there are places you can send the computer out to to delete the VATS, egr, rear O2, all kinds of stuff. you can do it yourself but the software is pretty pricey.
