Leanest cyl?
I agree, number 7 sucks.
Dont have any idea why but it does.
My #7 went while making a pass spraying last year.
Everything else looked fine and the A/F overall was dead on.
Luckly I had planned on this happening and it was no big deal.
77 bottles on Nitrous on a stock bottom end and I never sprayed less then a 150 shot.
Well at least 77 reciepts of nitrous bought, I probally lost a reciept here or there.

from what ive heared, the shape of the intake we have directs more air towards the #7 intake valve that the others. therefore, all 7 other pistons may be getting the same amount of air and fuel, but #7 will run lean because it is getting the same amount of fuel and more air.
Tony Mamo the AFR heads rep recently lost his H/C LS1 due to the #7 taking a crap. LSone, is right on the money. The intake design sends almost direct air to #7 causing it to run the leanest of all cylinders.
