Your right Jeff. But compare the (race) 427 to the 6.1 hemi. The hemi has the smaller TB, around 2 pts less compression, less cam and the 427 is rated less than 1 hp/ci and the hemi started at more than 1 hp/ci. If you correct the 6.1 370/385hp to 427 inches and for the additional compression the 6.1 would be over 470hp.
The 5.7 hemi at 305 hp is likely closer to the 427 and everyone complained about the 5.7. If you correct the 5.7/305hp for compression and inches its about 400hp. The TB, valves and additional cam may be worth the other 25hp.
Why isn't everyone complaining about the 427/425 rating?
I can remember threads where Mopar (and Ford) folks were called immoral and unethical but I doubt we will hear that about the Chevy guys. And we shouldn't.
