I had a 460 in a '76 T-bird and it was so gutless and hard on gas that I looked to see if there was a hole in the tank. The only 460s I ever saw were the low-compression low-efficiency environmentally friendly wonders of the mid-seventies.
Yes, the BBs of that era were terrible. I have owned and driven BBs from the 60's thru the 90's and the ones from the very late 60's were clearly the most powerful. My '69 Lincoln made 370 HP and 500 lb-ft per the book, but that is NOT 370 HP and 500 lb-ft by todays standards, more like 290/390.
454s on the other hand came with up to 12.5:1 compression earlier and maybe 8 or 8.5:1 after the legislated changes. Some of the early engines were rated at over 400 H.P. and more than 500 foot pounds of torque.
Ford, GM and Chrysler all had high CR engines that made HUGE power and Tq numbers, but that was NET HP and Tq, no engine since about 1975 has been rated that way. One of the biggest mistakes people make is thinking 500 HP from 1965 is the same as 500 HP from 2005m it's not even close to equal. The 2005 engine is actually making a LOT more power at 500 SAE HP than the older engine was at 500 NET HP.
Does the 5.4L engine make that kind of power and torque?
If you are using the same measurement standards, yes. A little more HP and a little lower Tq, but very close.
2010 5.4L 3V = 310 HP/365 Lb-Ft.
2010 6.2L 16V = 385 HP/405 Lb-Ft (WAY more power, better fuel economy, smaller displacement).
