3.4 firing order different???

Found this info on another site:
"Firing order 1-2-3-4-5-6
L (Front to Back ) 2-4-6
R 1-3-5"

Firing order is same, but If I am reading that correctly, they are swapped sides from my 2.8 which has 1-3-5 on the pass side of car, and 2-4-6 on driver side, could use some input here..Don't see any reason why they would be different being more or less the same block...only thing I can think of is the starter turning the motor the other direction or something...

that site is wrong, 135 is on the passenger side, 246 on the drivers and it's 123456. all GM 60v6's are the same.

Thanks, I would think all 60/6s would be the same firing order, just caused me some concern and wanted to be sure, sooner or later I'll be able to finish up my swap...got the engine in the car but had to pull the transmission...don't feel like having intakes and dizzy in the way of transmission bellhousing to block bolts..

That is correct. Left side is the drivers side in the USA. L/R is as sitting in the vehicle.
