Hyup there is so much confusion, deliberate obfuscation, and perhaps outright lies, in the horsepower ratings,wars, and factory dyno's, that IDK, it's enough to make a guy cry.
Like others have said, let the track tell the truth; mph don't lie.
And don't even get started on shipping weights. IMO, the factory wasn't stupid. They knew doggone well the power numbers were out to lunch. And they knew racers weren't stupid either and would figure out real quick what was going on. And so the only way to reconcile the track results to the advertised power was to fudge the shipping weights, and make the insurance companies happy.
I wasn't in the board room so I have no idea what they did or didn't do, but I ain't stupid either, I took just enough physics in highschool to know bs when I see it. I think.lol.
I got "lucky" in 1970. That was the year Manitoba switched from private insurance to a government regulated insurance. I had just purchased a slightly used Swinger 340. Private insurance at the time IIRC wanted well over $1000 to insure it (I seem to remember in the $1200s actually), which for a grade 10 gas-jockey making like a buck-thirty-five an hour, was a lot of cash in 1970. They said with a 340 manual trans,it was racecar, and I was a high-risk teenager. Along comes the new MPIC, (Manitoba Public Insurance Company) and I think it was under $500. Hyup I insured my racecar for sub $500. Screw private insurance I said.
Yeah so I didn't report it when I banged it up a little now and then. I had no idea that 48 years later that car would be worth a fortune. By the time I was done with it, 4 years later it was worth about half of what I paid; Yeah she was beat-up pretty bad. And on; second engine, second trans, second rear gear, third or fourth clutch, and 7 sets of rear tires passed under her; man she was hard on tires!,lol. It came with a flat-black twin-scooped hood and a factory rear wing. FM3/PantherPink too.
