I wouldn't call a simultaneous build/release year a copy. From Wiki: 277 The 277 "Hy-Fire" was the first A-block engine, produced for 1955 in the fall of 1954 and sharing almost nothing but the basic concepts with other engines built by Chrysler
huh...I thought it was a mid 56 model year release, in the Plymouth. At least I did when I had a couple of them in 56 Plymouths. https://www.allpar.com/threads/mopar-a-engines.229951/
Who's measuring the HP. What are the rules for this contest? Who has the biggest PR department? Are all the numbers certified? Let's not forget that in the late 60s (early 70s?) there was a sorta set of rules for claiming a car's HP -- and they all took a dive.
Yep, from Hagerty's web site. The 300B of 1956 gained 12-volt electrics and the signature fins that were applied to all Chryslers. The Hemi V-8 was punched out to 354-c.i. and 340 hp, while high compression heads delivered 355 hp—more than one per cubic inch. The 300B set the world passenger car record for speed at Daytona Beach at 133.9 mph and 1,102 were sold.
I'm not Squirrel. They actually cross st 5250 rpm. It's due to definition of hp and torque and the mathematical relationship between them.
The dyno measures torque at each RPM . It does not measure HP. You have to calculate HP, using the formula HP = Torque x RPM / 5252 at each RPM. 5252 is the constant, which comes from the definition of horsepower (550 ft-lb/sec), divided by the number of (radians per second) per (revolutions per minute), which is 0.1047 If you do a little algebra, you'll see that when RPM = 5252, HP = Torque x 5252 / 5252 = Torque x 1 = Torque
Coincidence? I’m watching a documentary on scientific fraud and scams. Good stuff, greed and company pressure seems to be the common factor. Who the hell can we really believe?
OK Squirrel, here's one for ya... Why did the '49-'54(?) Chevs have an oval shaped exhaust tail pipe? Always seemed like an extra manufacturing step that did nothing...
Sorry, only this one time for me on this hilarious thread. This jumped out at me @squirrel when I read the question I've quoted. Why did the Vette's keep that style front suspension over GM's new design for the 55-57 cars? It just seems a bit backwards for a "Sports Car" vs an everyday driver to me.
The vette was a low production car, and it costs a lot of money to design a whole new chassis for a sports car, especially if you want to make it beat all the other sports cars. I expect it was just a matter of economics. The chassis design had to last for a long time, to recover the design cost.
I looked at a pic of a repop exhaust pipe set, the tail pipe is flattened....I just wanted to see what he was talking about.
