I thought the LS1 was used in 2002. Doesn't the LSX motors have a coil pack for each spark plug?
1-8-4-3-6-5-7-2 would still be the firing order regardless of whether it has a distributor or not
yes it does but the order in which they fire will still be the same 1-8-4-3-6-5-7-2
"The Generation III V-8 engines replaced the LT family in 1997. These shared the same bore spacing (4.4") as their cast iron predecessors but almost everything else was changed. The bore was reduced to 3.9 in and the stroke longer at 3.62 in. The engine blocks were cast in aluminum for car applications, and iron for most truck applications (notable exceptions include the Chevrolet TrailBlazer). The engine also introduced coil-on-plug ignition. The traditional five-bolt pentagonal cylinder head pattern was replaced with a square four-bolt design, and the pistons are of the flat-topped variety. The cylinder firing order was changed to 1-8-7-2-6-5-4-3, so that the LS series now corresponds to the firing pattern of other modern V8 engines (for example the Ford Modular V8)." http://en.wikipedia.org/wiki/GM_LS_engine
Micheal is correct with the firing order of 1-8-7-2-6-5-4-3 for the Gen III engines.
