I was wondering if anyone knows what the feul consumption rate is for the 261 straight six I have been reading up on the engine but with no results for the feul consumption have shown up if anyone can help or knows someone or something that can help answer my question that would be great thanks !
How many miles a year are you going to drive your '61?
If not many, I wouldn't worry about it.

depends a lot on what gears are in the rear end?? City or Hwy. driving? I'd say 57 Pathfinder is pretty close for Hwy mileage with 3:08's to 3:36 gears!!

Ethan, is your car a power glide or a stick on the tree. If your 261 is in "perfect" tune and i do mean perfect tune, it is not that much better than a 283 with a two barrel. These motors like the 235's were never that great on gas. You have to be light on the foot and keep that motor running like a top ,to get half decent mileage. The Power glide offers less gas mileage than the stick unless of course you rev the six just before it blows, when you shift. I am only guessing but you should get about 12-15 in the city and 18-20 on the high way............. more or less. I have owned many of these sixes and they were never super stars for fuel consumption. Good luck and cheers mate. George
