Much debate on this for the V8 as well. Some are considering that the drive train losses aren't what they used to be (approx. 15%). For instance, our SS A8 dyno'd 401/403 stock. At the usual 15% loss calc, that would put us at 460/460 which is slightly higher than the 455/455 advertised. This dyno with the 15% gives you 281. Maybe the 15% is too high with todays transmissions and drive train?
