Blue Flame is the passenger car designation. In a truck, it would be a Thrift Master.

Oh, it also has on the valve cover "Blue Flame 140"
Is the 140 refering to the horse power?
Is it a 235? It is in a 1957 passenger car. What would be the difference from a Thrift-Master and the Blue Flame?

Yes, 140 was the horsepower. It is a 235, and should be a hydraulic cam engine. Generally speaking, solid (truck) vs. hydraulic (passenger) lifters is the main difference, depending on year. Some years, an automatic equipped car would have a different cam and a bit higher compression for more power to make up for losses in the trans. Otherwise, they are essentially the same.
According to my research, the Thrift Master name ran from '47 to '62. The Blue Flame name ran rom '50 ('50-'52 on Powerglide only)-'62.

Not all Blue Fame Sixes ran at 140 horsepower, but they were higher horsepower than the Thriftmaster truck engine and the standard automobile 235. As stated by LONGBOX55, the Blue Flame Sixes were put in Powerglide-equipped cars, and all but the Corvette Blue Flame sixes had hydraulic lifters.

Here is a Blue Flame 115 and the 1953 Blue Flame 125.

Here is a standard 106 hp Thrift-King 1953 automobile 235.

The 1955 Blue Flame Sixes in automobiles (not Corvettes) produced 123 or 136 hp.

The 1953-55 Corvette Blue Flame Six had mechanical lifters and produced up to 150 hp.

Thanks for this thread and information.

As I looked at the throttle linkage it is different from what I have. I believe that I may have bought and will put one of these engines in my 55 2nd. I need to find the swing arm between the push rod from the gas peddle and the vertical rod up to the carburetor.

I need to put this request in the parts wanted section. Can anyone help me with description?

TIA

140 is the correct hp spec for a '57 Blue Flame. It's also the hp spc for the Thriftmaster version as well.
