    OK well I completed the top swap. The car runs and runs great. The SSAC headers were a bit of a pain to install. I am going to take the crossover off cut and weld VBAND clamps connections to it as I couldn't get a good fit no matter how hard I tried. My friend was able to make a custom mounting bracket for the ICM and coils that worked pretty well. I found two bent valves on the L67 heads but when I bought them I knew they came from a car that the bottom blew in so I assume the piston smacked the valves. It was no big deal I just took all of the valves from the L26 heads and swapped them into the L67 heads. The first attempt to start the car I had the front and rear plug order swapped so that was a fail. I could tell from the sound that it made it was just the firing order, swapped them around and it started right up. the front of the engine was making a tapping noise which my friend quickly realized was a lifter filling with oil. so after checking and checking again and then on last time.. road test.. I used an Elm 327 Bluetooth adapter and Torque for Android to scan my car. I built 0.3psi of boost and it only bliped 0.1 KR. The lack of boost was cause by a nipple on the back of the gen5 that i have no idea where it goes so vacuum leak.. I am going to get some vacuum hose and a bolt and plug that thing unless someone tells me otherwise. The only reference car I had was my moms 2001 GTP and the gen3 didn't have that vacuum connection. I bought a GTP MAP for my car but on the paperwork ZZP sent me it says GT MAP so I just left the GT MAP in the car. I do not have a BARO sensor that I saw on one of the GM diagrams.. but wouldn't I not need that as the MAP does the same thing? Will post what little pictures I have soon
