Yes, I'm here. I'm currently in the process of installing an L33 5.3L into my Baby. Ive had the pleasure of owning her for almost 8 years. Reading this thread has terrified me and now I'm afraid I've bitten off more than i can chew. I'll definitely be bugging you with some questions if you're still around for it. ill post pictures of my progress as it happens.
So far I have purchased the engine with all accessories, wire harness, and stock computer. I've also bought a 4L80E transmission (not the T56 magnum i wanted but what i could afford). Tonight i ordered the Torque Converter. I don't think my build will be as nearly as nice as yours G-Tech since I'm rolling on an EXTREME budget but I'm very excited to "upgrade" to a V8 with 300+ ponies at the crank.
