I'm 70 years old and been a Mopar fan all my life. I've watched tons of Nick's videos, but after watching this one...... I think I've died and gone to heaven!

Smooth idling big bore big hp mopar. Those manifolds not only work well but look great. Nice work!

To see the joy that engine brings you is heartwarming. She is beautiful! One-of-a-kind

An additional 102 cubes, aluminum heads, a more aggressive camshaft, and the manifold's numbers came that close to the headers?? That is truly astounding!! Great work, Nick!!!!

This show is for me. I love the detail. Nick is the greatest

The perfect factory design. Just like the 413 wedge.

those manifolds are a work of art .

Factory headers without the problems,loose bolts! Engines a beast! Great job nick!

You didn't even comment about how smooth and quiet that monster sounds. It ppurrs like a cat. Very impressive power from this beast.

You just got to know the stares in the heavens and the gods of Mopar Muscle have come together to Bless Nick and his years of service and dedication for keeping all things muscle alive with this gift of power and torque in HIS 528 HEMI . This is why I call Nick the Wizard of Mopar muscle .

What an absolute work of art. I was in the hospital for 6 months last year and missed this video. I’m glad you reposted it. Thank you Nick.

Those are such a nicely routed set of manifolds, almost look like headers, I didn’t figure it would lose a lot of power but I thought it’d lose more than it did. Very impressive 👍 you’ll have to beef up the chassis in whatever car it ends up in or you’ll be twisting cars in half!

The interior noise level will be so much better and still have that sound of intense power. And none of that header scrape that happens on some driveways and parking lots. Great job Nick!

Nick , just a beautiful Engine !!! I was glad to see it didn't hardly lose any horsepower or toque . 528 Toque Monster as you say . The people are going to love seeing the 528 setup at the car show . Hope yall will be doing a show from there . All the best Nick .

Those are some slick looking manifolds.And the best part is they REALLY work.This was fun Nick, Thank You for sharing!

Wow Nick, the whole shooting, editing, voice overs just get better and better, just like your engines!

I love this engine even more! Great job Nick, this is such a smooth running engine for such a monster. This is a total sleeper candidate.

Another benefit of the cast manifolds is less heat in the engine compartment. Therefore, less heat back through the firewall. Great Job Nick. Wish I could get you to build a stroked 440 for my 86 Dodge Ramcharger. I have a 440 in it, motorhome 76 engine that I rebuilt for cheap gas. I love it.

I think that the design of the manifolds is the key. I think that the front cylinders blowing past the rears creates a venturi effect drawing gasses out of the rears.

This really is amazing. Almost no power loss & just a few pounds of torque?!?! Incredible. Great work guys 🤙

Another Monday and Nick's 528 Hemi, still on the Dyno. I'm very anxious to see what this torque monster can produce with stock exhaust manifolds. Let her rip Nick, This is awesome!!!

Excellent results those engineers at Mopar were no dummies they knew those exhaust manifolds would flow and they look beautiful those things are awesome headers are a pain in the ass but sometimes can't get power but the exhaust manifolds are much better and it's super simple and they're not going to leak and all that stuff have a great day thanks for doing this

those old Chrysler engineers did a great job on those exhaust manifolds. I have always heard that there were certain exhaust manifolds that were just as good as headers, those Heli manifolds, the old 423 max wedge ram horn exhaust and the old chevy big block corvette exhaust manifolds.

Nick that 528 Hemi Looks as sweet as it Sounds and Complete with Exhaust Manifolds and NO rear seal leak either with Pretty Impressive numbers too. George that intro and music was fitting for this sweet engine.

Outstanding! Looks beautiful with the manifolds!

Gotta luv Nick's enthusiasm..

Wow! I’m blown away , can’t believe it didn’t lose that much .. wasn’t expecting that nick ! Great job as always

Never seen Nick so happy :) Would love to see this engine run with a Tunnel Ram and a roller cam !

the engineers at Chrysler really understood what needed to happen with the exhaust end of things, what a beast considering the era of its conception thanks Nick.

If I Owned the beast, it would be going into a 69 Road Runner! Great work Nick!

The factories could design some very good manifolds. I remember reading an Pontiac 455 exhaust manifold vs header test years ago, and the engine only lost a few horsepower and torque at 5200 rpm. They said they almost fell over at the results.

Love it, Nick. You know it needs a 70-71 B body to go in now. Then again, that kind of torque would be so cool on a 70 Chrysler 300 Hurst clone.

Nick is like a proud Hemi papa 👍

Just got myself a cup of coffee and now I'm going to set back and listen to the music of this monster HEMI.

You guys just keep hitting the ball out of the park. Incredible and so exciting to see what is next every week. Nothing compares to Nicks Garage and to the dedication of all the people who care. Thank you

This 528 Hemi will pull stumps all day long...damn the torque is impressive!

A Hemi never gets old A 528 Hemi is only for the bold This is a real hard rocker It's gonna be an astonishing shocker Manifolds fitted like the headers never existed This is how petrol heads get their spirits lifted It's got the humble rumble It's the king of the jungle At Nick's Garage they never fumble or stumble Nick is making proper use of his dynamometer bundle The manifolds for Nick are the correct application Barely lost any power in this situation With whatever you choose you can't lose because a 528 Hemi causes utter devastation Thanks Nick Big ups George Shout out from London

I hope you name your newborn beast Frankenstein because you Dr.Nick have definitely created a MONSTER!!!!

Those exhaust manifolds are nice. And the way they are curved seems like would flow pretty good. Nice video Nick!

I think the cast iron manifolds flow almost as well as headers but I think the cast-iron has a thermodynamic advantage. So you lose a little efficiency in one respect and gained a little efficiency in another. I love cast iron. Headers cook everything under your hood. Rock on Nick

As far as i remember these 528 engines were sold as aftermarket parts to be put together regards ❤️👍

This is why Hemi's are legendary!!!!!

You keep at it Nick! Surround yourself with good ppl and don’t slow down! Just beautiful 🤩 Nick !

I am not a Mopar guy, but who couldn’t love this engine? Hat off to you, Nick.

WOW what a HP MONSTERand with stock Manifolds.....What can i say but Nick you are an engine building expert first class...... Thanks so much 👍 Shoe🇺🇸

Fantastic job on the build. You've proven again that manifolds are quite sufficient for any street rod. The loss of a couple of horses is a small difference on a big ship.

Another exceptional build, Nick! Well-done, Sir.

CONGRATULATION Nick. THAT is a Very Impressive engine setup. From New Mexico, USA.

That water pump wiggling around like it is was wigging me out. Lol

Hi Nick and team. That's such minimal losses after fitting manifolds ! And such great looking manifolds, that actually work. You gotta love that Nick

That’s an incredible engine you built Nick. Can’t wait to see it, and you as well as George and your Kowalski Challenger on Saturday 👍🏻

Love your videos. You're like a doctor for engines. ***** DOCTOR NICK *****

I have watched for years I think this is a favorite George is in sync with Nick A+++ production values

Chrysler did their homework on those manifolds !

528 cubic inches? Can't get my head around that in these days of 100 cubic inch econoboxes. The sound of that huge V8 revving out to 6,000rpm like that is spine chilling.

Good evening guys!!!! VERY IMPRESSIVE performance with exhaust manifolds!!!! That’ll make an EXCELLENT street engine for cruising and the occasional ‘boulevard boogie’ should some unfortunate soul decide to ‘call you out’!!!! Terrific piece and great vid work as always, George!!!! Great week to y’all up north!!!!

You always impress me. Nice work as always. Don't ever quit doing what you do. Thanks for taking us along.

Nick, You are a world Mechanic.

Regarding engine water temp: I had read somewhere that in NASCAR they run their engines at 195-degrees (F) and they get free HP by running hot. That's what I read.

Nick, Fantastic job on the monster Hemi. That's a wonderful engine & incredible output for a stock appearing engine & I'm sure it has great street manners as well. Nothing better than a traditional Hemi.

2:34 everyone always forgets to tighten those bolts on V belts... but, usually don't see those type of mounts on a serpentine belt set up.

Funny how a lot old Mopar engines fresh or old you need to pump the hell out of the throttle to start them , i have a 318 one cylinder is down a bit , today i started it after a week of it sitting around , i didn't even get in it just turned the key BOOM fired in a sec , no pumping the gas , its a 600 holley , tuned to perfection no puffing smoke . Within 2 to 3 secs click into drive and im off even in winter .

Those are great numbers with the manifolds on it... Another great vid Nick..

Very impressive #'s. To me it's not worth the headache of fitting headers in the car all for an extra 8 horsepower and 20 ft-lbs of torque. It's still a monster with more than enough power..

Melling....made in the USA. All these people having lifter failure , I think these are the ones to buy. Great outcome Nick.

hi Nick. the man at ViseGrip gauge was working on a charger. he had a maine seal problem. he got with one of the mechanics from a dodge stable in the south .they have an aftermarket seal that is designed for racing. NASCAR Racing. give him a shout out. love what you do.

Awesome engine Nick, what a beast! Those are gorgeous exhaust manifolds, heck yeah, factory manifolds is the only way to go!

Giasou Nikola, What a beast, beast with a capital “ B “. Watched this episode Wednesday after work with Feta, Home grown tomatoes all washed down with ouzo. The Greek 🇬🇷 thing to do whilst watching Nick. Now the Tsipouraki will be coming your way soon. I just agree with everything Eugene is saying he just writes it so well & he speaks for all of us. Fantastic result, not very often we hear from you “ This is freaking me out “. Can’t remember the last time you said it. Nikola can you please put a side a printed copy of the Dino results with header & with manifold & also a booklet from Motorama if you don’t mind. I can’t be there in person but I can be there in spirit. I just need to get to Canada & the USA sooner or later. All the best in Toronto, safe driving I hope my cousin goes this time. Cheers Your number 1 Fan in Australia. Louis Kats from Melbourne, Australia. 👍 😊 ✌ 🇬🇷 🇦🇺 🇨🇦 🇺🇸

As usual you never fail to make me go "holy #@&×" hahaha. I just can't get enough of this content. You all do a fantastic job. Thanks so much for all the passion and dedication it takes to do this😎✌️

That’s why the hemi was so good in a stock form. Great manifolds and air cleaner

I agree… those are really beautiful looking manifolds, for such a minimal loss why would you want headers. Actually, I think they look better than headers!

I think those numbers are good enough for anyone but a complete maniac, Nick!

That is a Monster, like to see that launch and hook in a car with sticky drag slicks. It would be pretty brutal on a stock drivetrain.

... G'day Nick, this 81year old is impressed. I worked for Chrysler Australia in the 60s on the Royal, Vidette, Valiant, Dodge, and Mitsubishi, both at Mile End and later at Tonsley Park in the Paint Shop, driver's side, final colour (no clear in those days). Cheers mate, Malcolm.

Another great video Nick! Anything north of 500 cu in is a beast, yours is a Super Beast!

That motor sounds like it means business. 👍

I love this channel. This guy can tune an engine to the percentage of a HP. Id like an engine from Nick.

I guess next time I watch this, I won't comment on the video before it is finished. This whole video is amazing from beginning to end! It just amazes me how little difference the manifolds made by comparison to the headers. Agreed, keep the manifolds! No hassles or worries about fitment. I was thinking that Nick was keeping the engine at over 2000RPM at idle. Then he brought it down to 1600 (which I thought was lower limit..) THEN he brought it down to 1000 WITH Vacuum! That is one AMAZING engine!

Much love to Nick and the crew. You guys keep the dream alive!!!

You’ve got a hell of a good drone pilot.

the thick cast iron of the manifolds holds in the heat of the exhaust gasses in the passages, so even though long tube large Dia. headers made slightly more torque, headers radiate more heat away from the pipes, cast iron manifolds keep more heat in the pipes and THAT increases velocity, resulting in more power. If the headers were smaller Dia. or smaller collectors etc they would probably make less power than the cast iron factory manifolds, which are essentially cast iron headers anyway. Awesome test!

Those hemi exhaust manifolds are probably worth more than my entire car

those OEM Hemi manifolds are some of the best designs ever - not surprised they lost so little performance. No way I would put headers on a Mopar Hemi car with the way the OEM perform

I absolutely love this stuff. Even the way you use the dyno. I'm learning so much. Thanks man. Hello from Louisville Kentucky.

A good pair of manifolds for sure, thing is the way castings work or are made no two will be identical so could be why less loss of power. this was a great set . congrats on the great work. as a side note Smokey Yunick invented a way to internally sand blast manifolds and heads with a sand pump basicly , later used by detroit on some motors and is called extrude honing.

Nick you're going to have to hire security at that show. I feel you are going to have a huge influx of fans at that Toronto show.

Love Nick's videos wish I could hang Out with the guys and witness him unleash the beast! That cam is nice!

Fantastic engine ! Have a fun and safe trip to Motorama, Nick .

Most manufactures had special manifolds for high performance. On a street car that is driven they make a lot of sense. Loose bolts, rust, exhaust gasket leaks are nonexistent. Our 1972 Pontiac T/A has manifolds we had ceramic coated. We think it is the best long-term solution. Plus, ground clearance is not an issue either.

Awesome Elephant! Only at Nick`s Garage!

What a beautiful beast! Congratulations with the success of making this beast!

What a Magnificent Engine!

I must say the combination of Nick and George is not something that comes along very often

Id love to hear your opinion on the Black ghost, such a rare and unique dodge 426 challanger.

I recon the manifold fit easier than extractors, sounds like a sweet engine, thanks for sharing, all the best to yous and your loved ones

Six hundred horsepower naturally aspirated, that sure is something to behold. The trick is putting all that horsepower to the ground though. It's going to take some hook that's for sure. Either way though it'll be a tire prover. Thank you so much for sharing, love hanging out in your Dyno room.

I've been around Hemis most of my life an not once did I see a 528. What a monster.

Just goes to how that Chrysler knew what they were doing with those exhaust manifolds.

Congratulations Nick and George! 🍻

Big block mopars had the best factory exh. manifolds in the industry . I had a 69 383 road engine , I put headers on it and it didn't make a pinch of difference - biggest mistake I made , plus they were hard on starters , the heat baked them !
