On the Calibrated Clayton Dynometer several vehicles that the Hot Rod Boys owned were tested.
1) A 375 hp advertised 396 1966 Chevelle made 285 rear wheel hp.
285 hp times 1.15 = 327 engine horsepower. the 15% adder is the typical drop from engine to tire hp loss.
The 375 HP rating was probably correct if you tested the engine without the water pump/fan drag and the accessory drag.
(Power steering). Looks Dead Nuts on the money to me.

I dont claim to be an expert and have no problem with your disagreement... as state, I was under the understanding that was the case.... I've read ( interweb facts of course) that was the case...
I drove a bonestock 68 bird with a 400 and It sure felt like more than 330ish... seat of the pants kind of thing..
