I mean in theory those monster 455s in factory stock form should completely trounce the coyotes measly 302 cubic inchs in the HP department??? Right?

i'll bite. how did the pushrod 5.0's compare for power to the 455's in 1971?

Best motor in the world. 123.5 HP per liter. Are you guys even trying?

You are limiting yourself to just car engines now. When you take a motorcycle engine like the one in the ZX-14R, then that Honda engine is just an antiqued POS with only 120 hp / liter.

In 69 they might have had some competition.

And blue,
the 69 Boss 302 and Z28 were both well underrated @ 290hp.

I used rated HP because I've read the chevy 454 and the 2013 boss 5.0 are both under rated from the factory. I think the tiny little coyote 5.0 did pretty good considering it's giving up over a 100 cubes.

1970 455 Pontiac = 370BHP
1970 455 Buick = 360BHP
1970 454 Chevy = 450BHP
1970 455 Olds = 350BHP
2013 boss 302 = 444BHP

my point was, in the "no replacement for displacement" argument is that you can't fairly compare a new small displacement engine to a 40 year old big block and say that we don't need cubes anymore.

if someone made a new DOHC with tivct on a 455+ cube engine you can bet your ass that it will make way more power than a 5.0. in the end cubic inches always mean more hp, apples for apples.

631 hp and 468tq N/A 8k redline engine = real winner.

And gas engines with big bores are especially hard to get to pass emissions (to many places for unburned hydrocarbons to hide). Why Ford and Dodge gave up big blocks and went with V10's, for a while anyway.

will it? probably not. but GM seems to be doing quite well with it's bigger inch engines.

the hp\ltr thing is completely irrelevant in real life. what matters is actual fuel economy, weight, power, cost of production and emissions. GM and ford decided to take two different routes to the same finish line.

I had a 2011 5.0L 6-speed manual GT. It was very fast with the 3.73 rear end. What bothered me was I would lose 1 quart of oil between changes. Ford's factory fill was conventional 5W-20 Motorcraft and they claimed it could go 10,000 miles between changes. That is preposterous. When I told Ford about the loss of oil, they responded by saying it holds 8 quarts so losing 1 isn't all that big a deal and the reason we recommend 5W-20 is because the bearing tolerances are so tight you have to have a thin oil to get through them. I now have a 2010 GT500 and it calls for 5W-50 synthetic and doesn't lose a drop between changes. It is also, imo, a better built engine even if the design is not as modern as the Coyote's. By far the best thing about the Coyote is the block. I'm a fan of iron blocks, but the Coyote's was plenty stout. Unfortunately, unlike the Shelby, none of the internals are forged. My GT500 has an iron block with DOHC and 32 valves and forged internals. It could easily handle a bigger supercharger, but I have a very hard time on launches not spinning my wheels as it is. It is faster than my 2011 GT was, but not a lot faster for that reason....spinning tires on launch. If we did a 20 mph rolling start, this Shelby would smoke my old GT. Losing 1 quart of oil every change on a new engine does not inspire confidence. The Boss doesn't lose 1 quart. My Shelby doesn't lose 1 quart. I doubt the LS3 loses 1 quart. There isn't enough data yet to fairly judge the Coyote with regard to long term reliability , durability, and longevity. I did read on Mustang forums other GT owners were losing a lot of oil, too. Some went to a 5W-30 to see if that helped. One theory is the rings took longer to set on the Coyote than expected and oil loss would diminish with time. Perhaps. I've driven GM's 5.7L engines and they were great. Durable as any import, never stranded me, and at 190,000 miles, the LT-1 in my 1996 Impala SS had 90% of its stated factory compression. Push rod or not, GM makes a damn good V8. The Coyote is a big improvement over their 4.6L 3V engine. A stock GT can run with a stock SS, and that was not the case prior to 2011. I'm going to see if the engine I have now lasts like the LT-1 in my Impala.

I never had an issue with either of my 5.0 losing oil. But for comparison of the two. The 5.0 makes more power bolt on for bolt on. Its due to the compression of the engine and better flowing heads. Bolt on 5.0's have made mid 400whp now. I had a bolt on manual that made 460whp. Thats cammed ls3 camaro power. But staying n/a choose the ks3. You have 429 ls3 stroker kits available that can make 600whp. Only way doing that with the 5.0 is do a n/a cobra jet motor. And it cost you 18k. If going boosted go 5.0. I made 713wgp on my auto 5.0 on stock headers and obly 11lbs boost on 93 Octane. Do forged internals and return fuel system and easily see 900whp. Bad part is the coyote blicks when get at the 1000whp mark. They break because of cooling jackets. I have an ls3 now with my vette. And will push it n/a before doing boost or spray.

1970 455 Pontiac = 370BHP
1970 455 Buick = 360BHP
1970 454 Chevy = 450BHP
1970 455 Olds = 350BHP
2013 boss 302 = 444BHP
I read an article where they dyno'd a 1970 LS6 Chevelle auto trans and it put something like 250 HP to the wheels. No way it was making 450 net HP.
