but who builds stock displacement engines anymore? I just did Fair enough lol. What did you build? Well to be fair to you, the answer to who builds stock displacement engines anymore is probably mostly no one. I think many prefer a power curve focused on low/lower rpm. I'm the opposite. I like short gearing and higher rpm, so kept stock crank, ported the heads, single plane intake, higher compression and solid roller.

If you insure through Hagerty they give you motor trend for free.
MT jumped the shark years ago haven't watched any new content in 3 years.
Had it for free for a year with Hagerty. Did they renew it so you can get another year? I never found a link or email on how to get another year free.

Anyone watch it? Interesting results. Has me wondering if the cams should have shared the same lift but otherwise been customized to suite each engine best. How about a link to it so we can watch it They are having a Father's Day sale, $36 a year. Well worth it. https://www.motortrend.com/news/motortrend-app-fathers-day-gifts/ Deal only available in the US. Bummer. Can you subscribe at all? Some folks outside the U.S. cannot get it for any price. I wish you all would open the boarder up and let the racers come see us.

I did not know that Stage V made a dual plane? Somehow I suspect that a stock intake would have made more torque. https://www.hotrod.com/articles/mopp-0310-hemi-426-crate-engine-dyno-test/This is an article from Dulcich on Westechs dyno from 20 years ago. The otherwise stock 465 HP crate motor he used made WAY more low end torque with more cam with the crate motor intake manifold. How much do you want to bet its actually the same crate engine? Here's the spec's on that crane cam they used in that article. I run it too with a stage V single plane 2-4 manifold. Dyno pull needed to go up to at least 7500rpm.

So glad you wedge guys had no say so when Chrysler decided to build the HEMI. Really could that wedge run 1 2 3 4 at Daytona in 64? Indeed. We still have time to stop all this Gen 3 Hemi nonsense and re-engineer a head that makes some power.

Like I mentioned earlier
The 440 - 6 came out of a 1971 Dodge Charger R/T many moons ago
Steve Dulchich first car he said - That was the car shown on the episode of Engine Masters
It will go back into the car he said after all these years at some point - He pulled the 440 - 6 out when he was a youngster , one of his first engines he rebuilt and played with
The 426 Hemi is a Mopar Performance Crate motor circa 1994/1995
It is going into a AMC Gremlin on a future episode of Roadkill

Mopar's first V-8 was a Hemi. The only reason they got away from that design was simple economics. When they needed a horsepower boost, they went back to that design. When they needed a modern V-8 to compete globally, they again turned to the Hemispherical combustion chamber. And today, it is the design of choice for the fastest and quickest vehicles on earth.
Does anyone here believe that the current crop of Demons, Hellcats, and Redeyes would be as fast/efficient with wedges rather than Hemis?
Our wedges are certainly great engines. But the hemispherical combustion chamber that allows for a better valve arrangement is simply much more efficient. And when taken to it's logical extremes, cannot be beat. That continues to be proven over and over again. Any mod or improvement to a wedge head can be trumped by modifications to a Hemi head. The only times that a wedge head wins is when a Hemi head is saddled with half measures.
Now, it is a fair argument that in many applications (actually most applications), the additional complexity and expense of the Hemi design is not worth the trouble given the level of performance being sought. But then the argument becomes performance bang-for-the-buck, not overall superiority. Which is essentially the same decision that Mopar came to in the late 50s.
Master, again and still

The only times that a wedge head wins is when a Hemi head is saddled with half measures. I'm not smart enough to explain why but I remember Monte Smith always mentioning the Hemi was best suited to boosted applications. For N/A or on spray, a canted valve style head with symmetric exhaust ports was the best option.

It's because of the already "softened" chamber<<< I dislike that terminology--It's scalloped IMO. The HEMI has a factory scalloped chamber that widens the tuning window significantly under power adder applications--Basically the HEMI chamber is a slow burning chamber which is why when you add a second plug--things change so much. Hate to say it but a single plug wide open 170cc chamber is inefficient. J.Rob
