Case in point, we will be looking at two engines of comparable size; the Chrysler 345 introduced in 2003 and the Chrysler 354 introduced in 1955.
HP rating: 335 on the 354 and 320 hp (one model did 350 hp). Yes, one is raw while the other is SAE. Meaning, both of the engines are about equal since 350hp would lose a few hp with the addition of the various engine drive features.
Torque would be close as well. The 345 (5.7l) would be 335 while the 354 would be 385.
And this is using bare boned carburation on the 354 and fuel induction on the 5.7L amongst other improvements. If the 354 would have been equally equipped it would be closer to 450hp while the best the 345 can do is in 2009, the introduction of the Eagle Version of the 345 at 405 hp.
Now let's look at what has been invented since 1943. For the engines, nothing. Between the Aircraft Engines and Tank Engines, the WWII engines had it all including fuel injection, supercharging, turbocharging, hemi heads, high compression and they boosted more than 1 hp per CI which wasn't met in an auto engines until the 354 was introduce and then lost again after 1969. In order for the Ford Coyote to get that fantastic HP, it needed to use all of the old improvements.
Now, let's use the big brother to the 354 which is the 392 introduced in 1957 and ended production in 1959. It came out of the factory with at least 350 hp and one version made 395hp. And that was with carburation with no boost or special anything else. That's also the one that could produce 2000 hp if you equipped it like the hot Chevy, Ford or Chrysler engines. If you take one of the modern engines past about 1200hp, it becomes a maintenance nightmare while the 392 hemi could handle 1200 hp standing on it's head and without boost, could develop in the neighborhood of 700hp.
The 1950s borrowed heavily from Military Engines and we went through an entire Malaise era until the introduction of the 6.1 hemi which many others have equaled since.
Any ideas on this one, Motorheads?
