Lean tends to be the passenger side. Also the further back you go the leaner it gets. The leanest cylinder typically is therefore #7.

look at how the intake sytem is setup. all that air is getting crammed into the back of the motor and which one will receive the most?...#7. this would lead me to assume that a setup wehre u could tune each cylinder individually on FI would let you keep your stock bottom from blowing up aorund 550rwhp. because essentially its a lean condition really.. if im wrong guys, correct me.

Umm... pretty sure the #7 isn't on the passenger side

Going by the theory of intake air velocity and that the average flow of air is increased by how far back the runners are from the TB.

The drivers side should be the leanest as they start on the passenger side (set back) and go from there.

I think I will put it on the drivers side

Bleh...sounds good at least.

That's right, 1 is an odd number after all.

2 4 6 8 Passenger Side
Rear--->
1 3 5 7 Driver Side

Cylinder #1 is at the front of the engine on the driver side, all odd numbers
Cylinder #2 is at the front of the engine on the passanger side, all even

Its been this way since the first small block Chevy way back in the 50's.
