After I put IT to the test, I must say that the Spectre Performance 5485 Drive Train is a fantastic addition to any automotive enthusiast's collection.With its flawless performance and seamless integration into my Chevy engine I am extremely satisfied with this purchase. The improved power delivery and enhanced driving experience are undeniable pros of this drive train. However, the only drawback I noticed was a slight increase in noise output, but its a small trade-off for such remarkable performance. Overall, a must-have for performance car owners!
