If a truck had Hwy. gears and the 292 was tuned up right, what would be the best fuel milage one could get? This would be with a 1 barrel carb.

How would one improve it considerably?

I have a 63 C20 with a 292, 4.10, and 265/75 16 tires. I'd get about 11-12 mpg. I replaced the sm420 with a MY6 and the overdrive got me 15-16 mpg. Basically a stock 292,except RV cam, HEI, headers, Monojet carb. I've heard of even better with major work and a 4bbl.

I don't own a vehicle that isn't old enough to drink.

Thanks Larry for the info. What major work would it take to increase the fuel milage even more than 15-16?

The gentleman that claimed he was getting 18 mpg was running a bit taller gears 3.73 and a 700R4. His engine had LPG pistons, 260H cam, and head work including lumps. The carburetor was a 390 cfm Holley.

LGriffen, I am a Chevy V8 guy, but have a 292 in the current project. You mentioned in an earlier reply about Head work including "Lumps". What are you refering to as Lumps? Thank you

He is talking about a "lump port head". Go to YouTube and type in 292 engine or 292 lump port head. There is a great how to video there.

Also, the guys in the Inliners International Club have great resources about this subject. If you are thinking about building a 292 for a speed application I would also recommend the book by Leo Santucci "Chevrolet Inline Six-Cylinder Power Manual". You can order this book thru Motorbooks by calling 1-800-826-6600.

My problem is that I'm looking to build a truck for a fuel friendly daily driver. I found a good buy but it has the 292 engine. I will probably pass this one up. I would rather build a truck with a 235 anyway since I have a lot of extra parts. I don't know if a 235 is going to get any better fuel mileage though.

I've had a lot of disbelievers, but I get 16-18 MPG, sometimes more if I don't go on the highway.

I mainly drive in town, not a lot of highway driving.

Truck is a more or less stock '78 chev, 3.07 rearend, 3 speed, 230 w/monojet. Oh yeah, and HEI.
