I never gave Chrysler a second look until they came out with the Hemi. When I found that they crap valve seats and cams. I wish I never heard of the Hemi. I wish I still didn't love them. Even with all their flaws I still find them better than most engines. Sorry to hear its not going to be around anymore.
You got that right...cross port heads will always create higher levels of VE...inline heads like the LS Chevy lend themselves to create more low end torque, but will never match potential power output on the Gen 3. It's just a design constraint..pure and simple.
it's also it's Achilles heel, as you get up in to the 8+ RPM area, the exhaust pulls too hard on the Incoming intake charge and draws out Air/Fuel charge.
Apparently no one makes a coyote head (besides Ford) because the head is just that good. Difficult to improve on. If your on a budget, get second gens, if not, get gt350 heads.
The heads are not for 2009 or newer they are for 2008 and older gen 3 hemi’s. Putting the eagle heads on a non eagle engine isn’t straightforward so better aftermarket early gen 3 heads are easier. So they did their job.
@@aaronferguson47 I haven't put them on yet. I seen a CZcams video on them they gave a stock 5.7 60 extra hp from the stock heads no port nothing bolted straight on.
Thitek makes a head that will flow over 400 CFM at .600 lift at 28 inches....the mill I'm building now uses a set of Eagle heads., got them to flow 350 CFM at .600 lift...with a 2.14 intake valve, re-worked of course. And the heads cost me all of 300 bucks....insanely cheap horsepower.
@@ibraHemi Actually, I think the Thitek is a better head regarding flow #'s. With stock heads, there are casting limitations, when it comes to porting. The most I've seen Thitek's flow is 440 CFM with a 2,20 Intake valve at .600 lift....pretty darn impressive. Not sure with the Edelbrock heads.
Edelbrock always leaves a little horsepower on a table if you truly want to go fast you buy the good AFR heads that out flow these things and have better mid lift also
Does the heads have all emissions ports for egr solenoid .the ends of the heads look like port is not drilled..did Eric ever work for team c performance in bellflower California..
Bought a set of your Hemi heads 73cc combustion chambers......very disappointed in the flow numbers on the heads...claiming flowing better than the Apache Mopar heads and they DO NOT FLOW AS WELL AS STOCK!!!!.........Thitek is a much better head....does cost twice as much, but you get what you pay for!

@@EdelbrockTV This is from a post on the FB page "MoparStyle's Drag Racing - Classified Ads & Discussions" where I shared you YT video. He makes a good point. "Robert DeMan I've been told factory Eagle heads flow better than factory LS3 heads do. The cost of the 5.7 is quite reasonable, and becoming plentiful. The 6.1, and 6.4 still priced quite a bit higher. Most aftermarket stuff for the Gen III is comparable with just about every other engine. The cost of a stand alone wiring harness and a good EFI single plane intake manifold is biggest difference between brand. Arrow/Prefix don't seem to make the NASCAR Gen III intake anymore. Ritter has one but after machine work to clean up casting and get EFI bosses done it's around $1400 just intake. I wish Edelbrock produced a single plane Victor Jr. or Super Victor for gen3 in same price point as all other intakes." Looks like the Gen III Hemi's need a HERO to make a carbureted manifold for them. A market waiting to be exploited with all those cheap used 5.7's out there that will drop right into any of the old Mopars let alone all the other vehicles that they will fit in.
Your short block is too small to handle much more airflow, they just can't be made very big displacement wise and they already turn a ton of RPM with well done stock heads.
@@EdelbrockTV this one comes up "Long block only. OUT of STOCK." I think Ed was asking what the complete crate engine with the super charger goes for. I'm curious as well.
Out of the box they flow quite a bit more. The big question is how big can a Eagle head go vs how big can the Edelbrock's go. The answer seems very obvious, the Edelbrock's were designed to be ported extensively and the Eagle was not.
The new hemi block is much more rigid with a nice deep skirt, 4 bolt mains, has a dry lifter valley for less leaks, raised cam location to give it a much shorter, stiffer, lighter pushrod, it also drains the oil back to the pan off the crank shaft to reduce drag and oil foaming, smaller diameter lighter lifters, much better coolant flow characteristics to keep a more consistent temp through out the engine. To achieve all these improvements would have required major redesign of the SB and it would look almost nothing like the SB we know, this was basically a clean sheet design.

What's funny is I've heard the 5.0 Coyote referred to as a 4 valve "hemi" rather than a pentroof. Sounds like they've been playing fast and loose with terminology for a while now.
*Wrong* A Pent Roof and a Hemi are similar, the difference is a Hemi is limited to 2 valves per cylinder where as a Pent Roof is Four. en.wikipedia.org/wiki/Pent-roof_combustion_chamber Just the fact Ma'am, just the Facts.
@@IhateCZcams Actully a hemi can have 4 valves per cylinder it just can be really complicated. Something else that blurs the line between a hemi and a pentroof is some 4 valve engine used curved combustion chambers which resembles something in between a "true" hemi and "true" pentroof.
Very good product, but hey clowns, ever heard of Thitek? Your heads aren’t the only aftermarket ones, don’t lie, thitek’s been in the game for years, you can’t fake not knowing about thitek.
Is it just me, or is the video on this just crap? All grainy or possibly out focus. It’s like it was done with a cell phone ☎️?? I’d expect better than this from Edelbrock....
Engine combinations can vary. The chances of someone swapping the heads and not changing anything else are rare. Most people that will change heads will accompany that with cam swap and maybe intake swap and/or FI and calibration. This is why an HP number on something like this is not as easy to answer.
@@anoint426hemi6 With computer aided design (CAD) the test mule is no longer needed. That being said there is still no replacement for real world testing.
@@anoint426hemi6 Also stock to stock isn't what these heads were designed for so the gain would be as dramatic as it would on an engine that can really "Work" the ports.
Since it’s CAD, they should be able to know complete specs and recommend all matching internals for max HP. Yes, for several applications (boosted, turbo, natural aspirated, larger throttle bodies, carbureted, FI). For that kind of money spent on heads, I hope I’m given specs for my application.

Show us a Dyno we Hemi guys want proof. Edlebrock is super late to the game.
Proof and money😎
The advantage of a Hemi is not just the chamber, the cross flow is just as big a advantage.
