Hey all,

I decided to figure out, once and for all, just how bad it is, not that I care about the cost, just curious. I always put the pump in the same position and always stop the instant that the whistle drops pitch, so that's consistent enough. I had to run my numbers (including a 7% speedo discrepancy) twice to believe it... over a tank, I averaged 14.3 miles per gallon! And there were many "spirited moments" in that tank as well as a decent amount of light traffic situations. I am confident that on a day trip through country roads, she could see nearly 20!

So thats pretty good for a 70 year old car with a 35-year old WORN v8!

The pathetic thing: My 2002 Lexus ES300 struggles to average above 21 mpg, which is worse than her 2007 Honda Odyssey 8 passenger (160,000 mile) van that gets 25. Looks like the chevy is not THAT bad! If MPGs really mattered to me for more than curiosity, that Lexus would be the first one to go!

What are you guys (who cared to check) getting?

I get about 13.5 as close as I can tell, although I haven't rechecked it in awhile. Engine is a Blueprint 350 with an Edelbrock 600, 3.08 rear gear and 700R-4 transmission.

M beat up old 216 gave me a consistent 15 at 50/55, and with the switch to 3:55, gearing moved up to 18 or so, would still climb out of this valley on one of 4 6,000 foot passes in high gear with the exception of one curve on one pass which always required a slow down to 20 mph and second gear.

Just curious what rpm you are running at 60-65mph with that rear gear and the 700R4 in overdrive? And do you have a lockup converter?

Yes, I do have a lockup converter but no tachometer. If I had to guess I'd say 18-2000 RPMs but not sure. Somewhere around 60-65 is where the car likes to cruise.

Back in the day with my built 235 3.70 gear and M22 muncie rock crusher it was 8-12 at best. When i decided to restore the car in 2013 in wanted a little better mileage and got it. I have had 2 different engine combos in my car both being 261 versions with different cams and lots of head work running a 450 quick fuel carb 3.08 gears and a world class T5 best highway run under 80 25 ish on the power tour, next year different engine 18 ish best tank. The ol foot control will change everything quick.

As will getting tickets. In the late '60's, I was driving the Vette in my avatar. I had successfully outrun the Mo. Highway Patrol in that car, but had collected so many tickets, that I was 1 point away from getting my license revoked. Luckily Uncle Sam intervened and drafted me, and after some time in the Army I grew up.

I never knew it until about 1988 when 2 off duty Mo highway patrolmen came into my dad's boat and tackle store and said something about there used to be a kid that lived here around Tonganoxie that drove a hopped up 6 cyl in a silver car we called the Gray Ghost we never could catch him. I showed them a picture and told them it was me. They wanted to know how fast it would go , I told them the Wyandotte County Sheriff clocked me on radar by where the Kansas Speedway is now at 126 in a 70. I got away and only made it about 3 miles 7 troopers had the highway closed. There went the DL for 3 mo's HP got me at 101 in a 50.
I haven't run it out since it was redone in 2015 but have shifted out of 3rd at 105

Well, it was 1968, and I was on my way out of town... a town of 5,000, where the city cops had one cop car, and it was a 6-banger Ford. So I was speeding a little, on my way out, and I saw a bubble-gum machine light up in my rear-view mirror. I just pulled it into 2nd and stomped the gas. I was running a cammed 327, double hump heads and a quadrajet. I blasted away from the bubble-gum machine, but after a mile I thought, "Darn, that 6-banger Ford is keeping up real good." It didn't take long for me to realize who it was--our local Mo. Highway Patrolman, Ted Andrus, (now deceased) in his Mopar. I hit the paved back roads, and zig-zagged mile after mile until I lost him.

BUT... the story doesn't end there. Yes, I outran him, but I had just gotten the Vette out of the shop and the mechanic hadn't tightened one of the hose clamps on the radiator hose, and evidently it had been leaking. My temp gauge was climbing higher and higher. When I saw sparks kicking out of the exhausts I shut the engine off, turned off the lights and coasted to a stop. It took him awhile to find me, but he did. He thought I'd blown the engine, but I assured him I hadn't. He only gave me a ticket for Careless & Reckless driving, and I was fined $35. He was a good guy, and I never tried to out run a cop again.

I've got one of these.. Doing a bout 85 in 55 with a saturn back in the day, and saw him, he saw me and began to pull out of his spot in anticipation I would drive bye, but JUST past his spot was an off ramp to another express way. Gave it all I could through the curve, FLEW through a "no-u-turn" right after the ramp smoothed out to the other expressway, doubled back, got off an exit and then got right back on the other side when the light turned green,m heading in the same direction, and CRAWLED until I was visible again then floored it. He never found me, I was shaking all the way home and never did that again. Nothing like you guys in REAL cars back in the ACTUAL day, but still, "those" days of mine were easier than these

STILL not bad... I always assumed these got like 6 with v8s in them... never cared. My daily driver is the same deal. I get 22 usually. I have bought/sold Prius for the business and averaged 50, but i prefer my old lexus. Gas is just a bill for enjoying what you're driving, as for as I am concerned. Yet, i am amazed how well the 50 does!

On a serious note, with a manual trans and a 3:00 gear, I am hoping for 16-17. I may be kidding myself though. Time will tell.

I don't usually keep track of gas mileage, but on a trip out to the Black Hills of South Dakota, I did. It was about 600 miles one way. A couple of hours of 80 mph speed limit on an interstate, not my best mileage. otherwise mostly 65-70 mph speed limits. I usually always drove 4-5 mph above that. At those speeds I would get 19+, best tank full was 19.6. At 80+ the mileage would drop substantially, maybe 17 mpg? Keep in mind that I have a TBI 350, 700R4, and 3.73 gears. I wouldn't expect 17 mpg out of a carburated 350 without overdrive.

are you running the TBI? someone offered me a tPi but i figured i'd run carbureted. I've seen guys use TBI throttle bodies on other stuff like olds rockets and 265 chevs.

I have 3.08s so while i dont have overdrive, my revs are close to the same as yours i bet

Yes, Chevy factory TBI. When building my 50 Fleetline, I decided I wanted fuel injection. TBI seemed to be (to me at the time) the simplest, easiest, fuel injection available. I transferred engine, trans, and harness from a donor truck. I have no complaints. Engine rpm at 70-75 is about 2100-2200 rpm. With the lower gearing of 1st and 2nd in the 700R4 there is plenty of low end power.
