273/4 -318 debate

Hang on if you believe the 318 numbers , do you also believe all the other numbers?..... like the 4bbl 360 numbers, or the 390/410 hemi?
This argument is so old, and so rotten,..............

The 74 4bbl 360 had all the 340 stuff on it from the previous year. All of it including the same advertised compression ratio. So now, there it sits blazing out in 245 hp glory, while the 340 sits at minimum 275. How does 20 cubes less make 30 hp more, wearing all the same parts. Com'on;. that chart stinks so bad.....
Not to mention the sucked out Hemi numbers

Or the fudged 318 numbers. How does a 318 with 45 cubes more than the 273 make 50hp less with just the loss of 1 point of compression and a bit of lift and two tiny secondaries?
I mean I ain't the brightest candle in the package, but I can tell there is something fishy going on there.

Or how about the 440 numbers ? 40 hp from adding a 2bbl over a TQ? I don't think so. Going by the same ancient source How much power was given to the 340 6pack over the TQ? Was it 10 or 15 hp I forget. And now the 440 is claiming 40hp from a 2bbl with the same cam and heads?
Crimminy I need to put a 6-pack on my lawnmower.
