Stop in for a cup of coffee

Question: When discussing tuning my 660's on my tunnel ram big block elsewhere, someone replied with this, then my reply. Am I wrong or snarky? Nothing got said, just wanting other's views.

(Another Forum Member) I am willing to bet if you saw the A/F ratio, you might fall out of the drivers seat.

(Me) There is a good chance I would, but maybe I wouldn't. May be best not knowing. I read through so many people spending so much time and money over 12.5 vs 12.8 (made up numbers just for example) that they just go crazy. This is a toy, I get 12mpg (best was 15mpg over a 6hr drive) with 2 antique race carbs on a big block. Could I fine tune the combo, yes, and that is what I am trying to do. The car's reaction, drivability and spark plugs should tell the story. I am less concerned over a magic theoretical number. Every engine is going to be different, despite the same basic constants. SBC vs SBF vs BBM vs Hemi vs.....All each will have their own happy place. Then figure in gearing, weight, etc. I see it as the whole package effecting the running and the tune. I could hit a magic number, and maybe it will get the best overall fuel economy or help me pick up 0.010 in the quarter. I just want it to continue to run good and tune out the 10-20% that it is lacking.

Seems reasonable to me.
