LS3 vs 5.0 yote? motor only comparison.
Not sure if this has ever been dicussed but which motor could bring the highest hp with maintaining street driveability and reliabilty? N/A of course. If anyone has hard facts please post em but if its just opinion , that's fine too.

any ls engine

All motor...I would go with the LS, b/c it is just so deturned from the factory. 600-650 flywheel is probably all you will get from the Coyote and maintain drivability. After that you would have to spin it too the moon.
Boost...they are probably equal. But if you include the Boss engine the 5.0 wins for factory b/c of the forged internals. |
The Coyote is a much better engine from a technical perspective for performance, but it is limited by cubic inches. If there was an LS7 sized coyote, that would be one bad engine. The LS engine is a great engine for durability, but nobody on the planet Earth uses push rods in engines other than GM, and for good reason: Over head Cams are much more sophisticated and efficient for performance. An LS would not have a prayer against a coyote if the LS was limited to 5.0 cubes. The LS only competes because it uses more cubes to make up for its obsolete push rod design. Push rods are obsolete much like the flat head design was obsolete by over head valves. I don't understand why GM insists on using push rod engines. Of course, I also don't understand why GM insists on using fiberglass on Corvettes. No car company on Earth other than GM uses fiberglass--its used on cheap replica cars and bass boats. By the way, I am not a Ford guy. I have always been a GM guy but I do like the old Fords and Mopars too. Just keeping it real and honest. By the way, I am looking into buying a Camaro 1LE.

From just using quick and dirty math, a Coyote with cubes equal to an LS3 would put out around 550 HP and a coyote the size of an LS7 would put out over 600 hp with the same components (compression, etc.) as the current 5.0 coyote. That shows how much better the coyote is over the LS engine for performance. You can also look at the GT500 vs. the ZL1 to see the difference in HP, and it is well over 100 HP even thought the GT500 has the smaller cubes between the two. Chevrolet needs to dump push rods and go over head cam. Period. By the way, Ford was dumb to use an obsolete design solid rear axle on the Mustang when the Camaro used a much better independent rear suspension. Therefore, it is not just Chevrolet that was stuck in the past with obsolete designs. Of course, Ford learned from its mistake and is using an independent rear suspension the 2015 Mustang. Meanwhile, Chevrolet is still stuck with push rods in the new Corvette.

Most of the race cars and dragsters I see at the track have push rods

No replacement for displacement.

There's pros and cons for each. I do agree, though, that the Coyote engine is a sophisticated, well-engineered engine. The LS engines are good-ol', reliable small blocks. |

The more sophisticated forms of race cars (formula 1, etc.) do not use push rods, and no serious motor engineer will tell you that push rods have any advantage over over head cams for pure performance. If push rods are the way to go, why does no other manufacturer on the face of the Earth not use them? Look at any sports car made other than GM and you will not find push rods--only over head cams. |
Quote:
There are pros and cons to anything, but the pros of overhead cams greatly outweigh any cons versus a pushrod motor. It is not even close. Again, what other manufacture puts any push rod motors in their cars? |

At the gatornationals this year I watched pushrods engines producing horsepower in the thousands...watched the top fuel cars run over 300 mph in the quarter mile....didn't see any formula 1 cars there. Go NHRA

ls cheaper to get the power and more c.i.d. but ls has been around for a while. i personally know 2 coyotes that #7 has failed. and one of them is about to go down again. using tons of oil. if u look on their forums they are droppin like flies .
the coyote is a good motor. but it limits out faster the a ls. go with what u know tho. if u like and know coyotes go with that. if u worked on ls stuff and like it go with them. its all it what u want and what u comfortable with. |
