    Performance Timing Table Chevy 5.7 Liter TBI ECM 1227747

    Below is a .pdf document showing a performance timing table I've used on dozens of stock or nearly stock Chevy 5.7 Liter TBI engine using the 1227747 ECM. I strongly recommend Adjusting the VE Table when making any changes to the timing table! Use at your own risk!
