I have a new 502 Chevrolet Crate engine that I am trying to start. I carefully removed the distributor to prime the oil. I made sure to replace the distributor correctly. Some of the distributor wires came off and I'm wondering if the 502 firing order is the same as all other Chevrolet engines? Thanks

 

It's either 1,8,4,3,6,5,7,2 or 1,8,7,2,6,5,4,3

1,3,5,7 will be on the left bank (go by sitting behind the steering wheel)
2,4,6,8 will be the right bank

Good Luck.......
