datzenmike Posted January 16, 2019 Report Share Posted January 16, 2019 It said Blue Flame on it. I don't think it said Six. It was a long time ago. I think it was a decal. The Corvette probably used the latest upgraded available six in '53/'54, same as the later '57 fuel injection 283. They took an available older engine and souped it up. https://www.ecklersearlychevy.com/chevy-valve-cover-decal-blue-flame-six-6-cylinder-1949-1952.html https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=805417 https://www.rodauthority.com/tech-stories/engine/project-geronimo-evaluating-a-vintage-engine-what-do-we-do-now/ The Engine: A Historical Overview The first thing we wanted to evaluate in the pursuit of our overall goal of creating a daily driver, was the vintage truck’s engine.

'51 Chev Seems like the Blue Flame has been around a long time. Corvette just made it better. 1 Quote Link to comment

That is a later model engine, 63 or newer. ? 1 Quote Link to comment
goes2fast Posted January 17, 2019 Report Share Posted January 17, 2019 And I refer you again to the Chevy performance article; Chevy product planners had a different outlook. They reasoned that if the Corvette came with a manual trans, the public would view the car as old fashioned. After all, went the thinking, who wants to shift gears like they did in the olden days? So, from the beginning, a manual Corvette was not a consideration. Besides, the Powerglide two-speed auto was perfectly matched to what was then known as the Powerglide six-cylinder engine. The Powerglide six was a solid, passenger-car version of the 235ci Chevy truck engine that had been around since 1929, when it was known as the Stovebolt Six. It made 115 hp using wedge-shaped combustion chambers, hydraulic lifters, 7.5:1 compression, and a single-barrel downdraft Carter carb. The '53 version received aluminum pistons (a first for Chevy), full-pressure lubrication for the bottom end, and steel-backed inserted rod bearings. 1 Quote Link to comment

datzenmike Posted January 17, 2019 Report Share Posted January 17, 2019 I drove one once, not far though. The torque is unbelievable for pulling or ploughing snow. That round thing is the clutch and PP. 1 Quote Link to comment

What next, a whole page of pictures of a John Deere B engine ? What's wrong with a Johnny popper? They were amazing in their day! Our neighbor had 3 of them and you could hear them every time they were out in the field working. Too bad they don't put it under load so you can hear the true sound. The smaller round thing on the other side is the brake. Edited January 17, 2019 by goes2fast 1 Quote Link to comment

G-Duax Posted January 17, 2019 Report Share Posted January 17, 2019 (edited) I sat on one for many an hour back in the '60s. The early ones had an exposed flywheel on the left side, with finger groves on the inside for starting. To start, turn on the fuel, open the two petcocks on the sides of the cylinders (compression releases), grab the big flywheel, give it a good yank with everything you had, and hope it fired. If it did, close the petcocks real quick, because they were blowing fire at that point, and away you go. And the smaller round thing on the right is not only the brake, but also the flat belt drive for things like saw mills. Edited January 17, 2019 by G-Duax 1 1 Quote Link to comment
datzenmike Posted January 18, 2019 Report Share Posted January 18, 2019 Maybe it was the other side. 2 Quote Link to comment
