First-Gen F-Body LS1 Engine Swap - Generation Zap
|
We used March Performance's LS1 Serpentine Polished Aluminum LS1 Alternator, A/C & Power Steering Pulley & Bracket Kit (PN 20104)-say that three times fast. According to March Performance reps, the pulley kits are "CNC-machined from 6061-T6 aircraft grade aluminum, then all high-wear surfaces are hard coated to 65 on the Rockwell 'C' scale to increase pulley life. This results in surfaces that are harder than steel and two times harder than forged aluminum." They install easily, look great, and saved us from notching the subframe to mount the A/C compressor in the low-stock LS1 location. View Related Article
