The firing order is 1-2-3-4-5-6. The odd numbers are front to back on the left of the fan and the even ones on the right side of the fan. The distributor turns clockwise and #1 is at the 5 o'clock position. Hope this helps.

Runs rich and miss fires


Make sure the spark plug wires are on right (propper firing order), and check the TPS sensor. Are there any exhaust leaks or vacuum leaks? Did you use the original intake manifolds and Holley throttle body? If not you need to replace the PROM chip with the one from the donor car.
