It doesn't matter because it's not how the engine was designed. Just like coyote flow #s at .600 don't matter. So there is no discussion there.

Ls cylinder heads are amazing. Stuff conventional big block guys used to dream about for a race application much less factory street.

The modular stuff is cool to though. Flowing that much through that tiny port by the small bore.

As much as I agree the Hp/CI argument is bullshit, we still have to be practical in terms of the physics of making power with an NA motor. No matter how much the heads can flow or number of cams are used to move the gas/air mixture into the cylinder, there comes a point that it will not matter much in terms of compensating for a large CI deficit (~74ci).

On an NA motor, the amount of the gas/air mixture moving into the cylinder will be greater in a larger CI motor. This correlates to an increased amount of force exerted on the piston during the combustion cycle since the bore will be larger. To taking it a step further, if the stroke is longer it will also exert more torque or turning effort on the crank. This all correlates to power to the wheel.

The part of the CI argument that I do not agree with though is that nothing is preventing Ford from building a large CI motor and therefore, GM cannot be faulted for making more power using a larger CI motor. In the grand scheme of things, the Hp/CI ratio really does not mean much except for a greater volumetric efficiency. It will do nothing for you at the track or on the street.

With that said, greater HP/trq number do not necessarily mean that it makes for an overall "faster" car since weight, gearing and aerodynamics also play a big part in accelerating a car. In my opinion, I think this is what Ford tries to achieve with their performance cars: affordable, light chassis, aggressively geared (transmission / differential) and a "respectable" power-level motor. This combination seem to appeal to Ford since their performance cars produce good results at the track and on the street. In addition, sales are up.

Well. ....furds getting their *** fucked this year on the performance front. I would have to assume you like slower cars at that point.

I did not take preference to any faster or slower car. Just trying to look at this from different sides. As a matter of fact, I always have good things to say about both the 5th and 6th Gen Camaros. Things don't always have to be about taking sides, you know.

I wasn't taking sides. ...just pointing out the obvious after you used the sales are up bs.

To break it down further....the mustang gets trumped by all of the camaro counterparts performance wise.

The sales lead has NOTHING to do with the 5.0 engine, gearing, aero, or chassis. It's all about the increased cost of the new Camaro.

I think we all our in agreement that the 6th Gen is a handful for the 5.0. No doubt. GM did a great job with the LT1 and shedding weight from the Camaro chassis. I am sure Ford will counter though with something for the next model year. This competition is what keeps this interesting.

I really want to see a Mach 1 or some other model in between the GT and 350. The S550 has grown on me a lot since I first saw it at the NMRA finals in 2014.

LoL well no crazy chasing shoulder passing car splitting stuff. I like living and I dislike rock chips but running a big power car is fun. I'm in the Thib. Bayou area. Not too far from you.

Not bad I guess. I should be happy for my lame coyote when it makes more power than the on a in this test without cams.

Mine also makes more torque than this test coyote. I make over 400 lb-ft at the tires.

The dyno all around seemed low. 556 crank hp from an ls3 is more like mild cam only

Sounds like the multiple 2015/16 5.0's with 900 wheel as well. Nice! Pretty even.

I have a couple friends in Houma. We'll see what happens. My car is getting somethings done to it and then I'm moving out of state so not much time to play around on the streets.
