Welcome to the community.
I think you and URLOSN, a moderator here will get along just fine with all those cars. I thought at times he was starting his own taxi service or something, LOL. You have come to the best place to pick up on performance upgrades. We have a very nice and broadly based community of knowledge here, not the least of which is Trannyman95 (Dave) that is the nations best 4T65E transmission guy. We have several drag racers here and tons of people with a top notch depth of knowleged about these vehicles.
I hope that in all your restoration work, if you can, you take notes, pictures and such as that is an area of knowleged we need with regards to how to's and guides and such.
Look forward to seeing examples of your work.
