Hello everyone! I have a 90 SS my father purchased back in 2008. Sold it my grandfather and now years later both have passed away and I was fortunate enough to inherit this old beauty. Work as a mechanic but not familiar with tbi really so I am excited to read all the info! Here's my girl with 14k miles and practically untouched engine...time to get to work where it counts! Don't have much information on the history... trying to find information on verifying authenticity on being an true 454 SS!
