My uncle had a 427 in his '66 Chevelle that was a real similar build and he put a 4-speed muncie behind it. He figured that would be plenty strong, but he scattered that transmission in less than 2 months. Everything was brand new.
Basically the same engine I built for my Chevelle in 1985 except I was running flat tappets. I switched to square ports and could tell a big difference on the top, but hurt me down low. And either heads worked best at 37degrees. I believe the rectangular heads would make it to the 600hp mark. I loved watching this video on my big screen. Thanks Nick.
Funny how simply putting a 427 Chevy on gets everyone's attention and doubles your viewership...lol I love those valve covers and the engine sounds sweet. Great job guys!👍
Its great to know im not the only older man that still builds models. Great job on that build! I love to see the care you put into it! George, i can't wait to see yours back on the road!!
I had all three 50 yrs ago at one time or another,428 Cobra Jet, 440 Magnum Super Commando , 435 HP 427 with tri power in a Corvette, stock on stock the big block Chevy was king !
That’s a Nick build from the ground up. Starts instantly, engine sounds so crisp. George, your opening for this video was great. Have a great week everyone.
I’ve grown to really enjoy your show. As a prior owner of a 99% performance machine shop I appreciate some of the problems you encounter and work through. My family is now on our 3rd generation of engine building and professional racing. Many of the engines on the TV show Street Outlaws No Prep Kings is built by our family. I’m old and retired and spend my time watching different shows related to engine building and stumbled onto yours. We built hundreds of big block Chevys staring back in the mid 70’s when NHRA first started the Super Gas class we built dozens of 454’s which were perfect at day and time for the class. We didn’t have a dyno back then so I like to watch you dyno those mild performance engines to see how much power they have.

@@robt3305 The 427 was a 69 390 horse engine, somebody prior to me had sourced it and dropped it in the Camaro. I later took it out and replaced it with an aluminum head 468 that I built and put the 427 in my 69 el Camino.
Hi Nick. Since you are doing a Chevy engine. I think you will enjoy this. One of my best friend's was a top engine builder who also knew Keith Black. We had built a small block Chevy 350 engine. Compression was 16.5 to 1 cam was 675/326 3/8 push rods if I remember correctly and I think the cam was 2 or 4 degrees advanced single carburetor. Turbo 400 transmission with a 5500 to 6000 stall don't remember what gears in the rear-ended it was only a quarter mile car a 1967 camaro. Two ring pistons.
Nope ! .....Factory Chrysler '40's '83's & most everything else Done by 5500 revs thanks to Mopars lame short duration hydro "juice" lifter cams.....Just the way it was in the day.....
Enjoyed the 427 on the dyno Nick! One of my favorite engines. Mail time is fun to see what people send from all over and the effort that goes into it. That '64 was a nicely done model!
Great the way the 427 roars to redline and as soon as the throttle backs off it settles into a healthy idle like "what else can you show me?" That's a 10 second Camaro! Beautiful build Nick! Way to go George!
It has been a long time since I’ve heard the throaty 427!! That is sweet. When we heard that sound on the street… you knew it was special. Great camera work George!
A bare block that had been stored for a long time, from about six months to three years, somehow makes the block much harder. One of the secrets to an engine block lasting a long time depends on how nimble the engine block is. With the constant heating and cooling, the engine is constantly expanding and contracting of which the engine block eventually will warp. With an iron block that is aged, it is less susceptible to being flimsy. The same goes for your diesel engine blocks, of which they are thicker than your contemporary gasoline powered engines.
Came to the comments to find this observation. I agree, heavy valve train with a lot of potential flex and hydraulic lifters makes spring selection key.
1965 396 60 over to a 408. forged crank and pistons 11:1 comp, ported 98 CC oval ports, big solid cam, roller rockers, strip dominator, 830 Holley. Revs to 7,000, 4,200 RPM stall, 4:10 gears in a 1970 Nova. Them old Big blocks pull like freight trains.
Dr. Nick, fast story, right before I got my 1967 GTX Hemi 4 speed, I almost got a 1968 Nova with a 427, so thanks for the flashback, enjoy your model George, cheers.
That was crazy cool that someone would send you a model of your car! Nick! You got to get that motor done. Put it ahead of the line. That was really great of the guy to do that.
Perfect street heads. The square ports are good for high rpm,but with a carburetor on give me the ovals for the street. I'd like to try a set of squares with multi port FI but too old to get into all that now.
Holley 950 or 4500 1050. Tube the transfer slots for good mileage using a wideband O2 sensor. Progression Distributors to tune the advance for efficiency. It’s blue tooth programmable from your phone. 650 is in that engine.
One of the greatest engines ever developed. Its my favorite big block. My dream is to build a 69 Chevelle 300, with every option delete you could get in 69, drop in an L88 speced 427, with a Rockcrusher. Making it a tribute to a 69 COPO car. Only options i need in it, are a steering wheel, a shifter, a seat, a clutch pedal, and a gas pedal. Dont even need a brake pedal. 😂
Thanks Nick for the build and test of the Chevy 427, for we Chevy people (though I'm a Pontiac guy) That was an awesome mail edition, especially George's '64 Bel Air with the inline six! :)
Great show!!!! That 427 will get the job done very nicely😊. George, you deserve every good thing that has come, is coming, and will come your way!!!! Enjoy and great week, all!!!
Those AFR heads just proved why they cost so much. You can build a streetable combo with a reasonably mild camshaft and still make more power and be more driveable than a large cam/factory head combo. Nick, you hit this one out of the park!👍🏻 You should have a solid mid 10 second Camaro once you’re done.
fun times for sure. Tuning or just tinkering every weekend. Now it's boring -- plugs maybe once a year, oil and filter every 3-4 months. Modern engines just don't make the same 'thunder' and some even don't make any noise at all- some even make fake noise. Sacrilege.
When you're installing those 230 Turbo thrift decals on the valve cover. Don't peel them off, gently slide it off into place. You never pick up a decal by the edge it will tear. They are like less than paper-thin. Hope it works
If I remember right, the Yenko 427s were rated at 425 hp and 460 tq. It's amazing the uplift in performance you get from simply putting on more efficient heads, intake, and cam. I would love to do a build similar to this except using a 383-B Mopar to 426 Stroker and dropping it into a C-body to make a sleeper out of it.
That engine would be nice in a 69/70 Vette 4speed manual trans & 3:36:1 posi rear and chromed side pips. Don't forget the Police 12X2&1/2" non powered finned drums all round. Love those brakes. Never had any problems with them.
A petrol heads impression of heaven A big block Chevy V8 427 Designed to move alot of air Nick's Garage is ready to share George the owner is very generous for letting us viewers see a classic engine so venerous It's bound to have some power Every Monday Nick's Garage is bound to entertain you for an hour Above their competion they tower Makin em sour But when you got a car to fix you need people who know all the tricks Nick's Garage is who you're gonna picks Thanks Nick George and George for sharing an engine worthy of applause
Good afternoon Nick & George!! Another Monday and we have a 427 Chevy on the Dyno. This engine has some great parts, that should make plenty of HP for George's Camaro. My guess is that it will make over 585HP, and 600+ Torque. Always something different at Nick's Garage, the best channel on TH-cam! Here We Go!!
@@NicksGarage I really enjoyed this video George. Watching the 427 on the dyno brought back a lot of memories from back in the late 60's. I was a little off on the torque numbers, but I think that with the new distributor, and the 850 Carb, the 427 will make my predicted HP. George will have an awesome 68 Camaro with that motor under the hood.
Another awesome build Nick! Back in 1981 my brother purchased a crate LS6 454 from chevrolet. Unlike the production car 11.1 closed chamber head, the over the counter crate engines are 10.25 open chamber. My brother had it in his 1967 camaro 4 speed 3.73 posi. He followed chevrolet's power book recommended set up. For a super responsive throttle and acceleration a holley 830 annual discharge double pumper along with stagger jetting for the factory dual plane hi-rise intake was just perfect set up for the camaro. During that time many magazine articles swayed readers away from running rectangular port heads for the street stating that low speed will be sluggish. Well this was not the case for the LS6 454. The factory solid lifter cam was very healthy but no where near radical like the L88 or the ZL1/LS7 cam. That 454 had plenty of low end grunt! I was 14 years old at the time. It was that LS6 that forever got me hooked on big block power. I currently have 2 big block engines that run on pump gas (91 octane) one making 705 hp and the other all aluminum 955 hp. Sorry to be a bit long winded, just wanted to share my experience and story.
I wish he was closer , I’d love to buy the guys coffe and b.s for a bit. Nic, answered my question once and I was fan for life , I just enjoy this format so much
Superb build, Nick. George obviously put a lot of thought into building it, and it sure paid off. I hope he drops by the shop when it's installed in his Camaro.
I agree. My 427 was built in 1983 to rev and hold together and run on 92 octane pump gas and it’s been a great engine for me. It easily beat an LS6 1970 Chevelle SS .
Building a 427 with a 275/285 duration 530/565 lift with a hydraulic roller cam grind is 111 center line but setting it up at 109 with LS6 454 heads at 9.8:1 compression ratio, hoping for 560@/530 ftlbs @ 6500 rpm
My cousin had a '69 L72 with 4 speed. It was a beast and you had to be careful, it would put ya in the weeds in a heartbeat. Don't know what happened to it after he sold it.
When Nick was asking I said it better make at least 550 HP with those components. I think it's capable of 575 give or take a little. Water leak is when I commented.
I bet if you put a single plane on it it would pick up 10 to 15 horsepower I know it's not as good on the street cuz he wants low-end torque but if he was full out racing I would definitely run a single plane. Definitely good numbers for 4/27 always love Nick's garage
Hi guys, that looks like valve float at 6400. It needs a stiffer spring to go past there. Nice engine. I’d love to have any of these engines you put together. So fun to watch. Let’s make some noise.
I'm glad to see you doing a video on Chevrolet do a few on small block 327s I would really appreciate it thank you and you're doing a great job keep them coming. ✌️
Nicks constant is 1.32 so 432 cubic inches x 1.32 = 570 . Most builders would love to be able to build engines and get the results that Nick gets, consistently!
Needs ovate springs and titanium retainers. 800 cfm will feed it plenty. Would also recommend 1.8 rocker arm ratio on the intake side of the valve length is long enough. That should wake it up a bit more.
20:09 That's an odd drop off in power, likely the beginning of loss of valvetrain control. Those heads have a heavy intake valve, though not as bad as the factory 3/8" stem valve. I've witnessed severe valvetrain control loss, the graph falls straight down. This is just warning you it's not happy above 6400, and after listening to the owner wanting to spin it higher before this run, I would strongly suggest an ignition with a 6500 RPM limiter. Sweet graph with a very broad powerband.
I had good luck running Accel blueprint HEI distributors. Dial in the right curve and they were hard to beat for the money. That was back in the 90's though. I ran a Q- Jet as well.😁
My uncle had a 427 in his '66 Chevelle that was a real similar build and he put a 4-speed muncie behind it. He figured that would be plenty strong, but he scattered that transmission in less than 2 months. Everything was brand new.

This engine similar power to a stock L88 427... this engine likely a bit more tractable...
Had fun back in the 70's with a Corvette 427 / 4 speed , working as a service advisor at a GM dealership. What a monster for the time.
I have a 65 427 Vette sitting in my garage. Every time I take it out it turns into a car show.
Way too heavy for a Vette front end.
@RidgeRunner-sm1vs that's why GM put "big block" springs in the front....
Was it the L88 427 by chance??? Lol very slim chance lol
Funny how simply putting a 427 Chevy on gets everyone's attention and doubles your viewership...lol

Mid 11's takes more to run in the 10's. Back in the day a 68 427 Motion camaro was sold and advertised as an 11.50 car out of the box.
21:16 I know my hammer advances on a distributor and that looked more like 3 1/2 degrees of advance.
I sure love the idle sound from a big block.
The sound of that distributor cap going back on brought back memories ❤️
fun times for sure. Tuning or just tinkering every weekend. Now it's boring -- plugs maybe once a year, oil and filter every 3-4 months. Modern engines just don't make the same 'thunder' and some even don't make any noise at all- some even make fake noise. Sacrilege.
That engine is a BEAST! I love it! Thank you Nick.
That's a beautiful sound - Nothing sounds like a GM big block
Fuel coming out of rear vent 16:49 and 19:28 and every time after max RPM.
Hey Nick ... check the tiny WP crossover hose! I have had more than one have a teeny pinhole in it, almost impossible to find!
Those AFR heads are making a really big difference.

If I remember right, the Yenko 427s were rated at 425 hp and 460 tq. It's amazing the uplift in performance you get from simply putting on more efficient heads, intake, and cam. I would love to do a build similar to this except using a 383-B Mopar to 426 Stroker and dropping it into a C-body to make a sleeper out of it.
That engine would be nice in a 69/70 Vette 4speed manual trans & 3:36:1 posi rear and chromed side pips. Don't forget the Police 12X2&1/2" non powered finned drums all round. Love those brakes. Never had any problems with them.
I love drums too, but you know those vettes had 4 wheel discs since 65.
A petrol heads impression of heaven A big block Chevy V8 427 Designed to move alot of air Nick's Garage is ready to share George the owner is very generous for letting us viewers see a classic engine so venerous It's bound to have some power Every Monday Nick's Garage is bound to entertain you for an hour Above their competion they tower Makin em sour But when you got a car to fix you need people who know all the tricks Nick's Garage is who you're gonna picks Thanks Nick George and George for sharing an engine worthy of applause
Good afternoon Nick & George!! Another Monday and we have a 427 Chevy on the Dyno. This engine has some great parts, that should make plenty of HP for George's Camaro. My guess is that it will make over 585HP, and 600+ Torque. Always something different at Nick's Garage, the best channel on TH-cam! Here We Go!!
Thank you very kindly for joining us once again, Mr Eugene. We always appreciate your kind and knowledgeable comments. 💛
hi Eugene, with all the flooding down your way I trust that you and yours are safe.
@@NicksGarage I really enjoyed this video George. Watching the 427 on the dyno brought back a lot of memories from back in the late 60's. I was a little off on the torque numbers, but I think that with the new distributor, and the 850 Carb, the 427 will make my predicted HP. George will have an awesome 68 Camaro with that motor under the hood.
@@ericball6000 Hi Eric, yes we have had a lot of rain lately, but we are all safe. Hope you and your family are well.
Another awesome build Nick! Back in 1981 my brother purchased a crate LS6 454 from chevrolet. Unlike the production car 11.1 closed chamber head, the over the counter crate engines are 10.25 open chamber. My brother had it in his 1967 camaro 4 speed 3.73 posi. He followed chevrolet's power book recommended set up. For a super responsive throttle and acceleration a holley 830 annual discharge double pumper along with stagger jetting for the factory dual plane hi-rise intake was just perfect set up for the camaro. During that time many magazine articles swayed readers away from running rectangular port heads for the street stating that low speed will be sluggish. Well this was not the case for the LS6 454. The factory solid lifter cam was very healthy but no where near radical like the L88 or the ZL1/LS7 cam. That 454 had plenty of low end grunt! I was 14 years old at the time. It was that LS6 that forever got me hooked on big block power. I currently have 2 big block engines that run on pump gas (91 octane) one making 705 hp and the other all aluminum 955 hp. Sorry to be a bit long winded, just wanted to share my experience and story.
NICK'S GARAGE NUMBER ONE ALWAYS
I wish he was closer , I’d love to buy the guys coffe and b.s for a bit. Nic, answered my question once and I was fan for life , I just enjoy this format so much
Superb build, Nick. George obviously put a lot of thought into building it, and it sure paid off. I hope he drops by the shop when it's installed in his Camaro.
Greatest motor ever made.
I agree. My 427 was built in 1983 to rev and hold together and run on 92 octane pump gas and it’s been a great engine for me. It easily beat an LS6 1970 Chevelle SS .
Certainly better Engineered, the BBC and the SBC, than any of the Competition, well into the 90s
I know of a couple of guys that built a 560 HP 327 with modern heads etc.. you could do that with less weight. But this monster is a torquer.
Initially the 427 was rated at 450 horsepower then reduced to 425 horsepower. The 454 LS-6 was rated at 450 horsepower. They were both underrated.
awesome show that 427 sounds pretty good great video
Thanks 👍
Nick great job really cool motor them 427 are hard to come by there's days unless you buy aftermarket okay guys have a good weekend
Chevys are so easy and cheap to make power. They are the swiss army knife of engines!
Building a 427 with a 275/285 duration 530/565 lift with a hydraulic roller cam grind is 111 center line but setting it up at 109 with LS6 454 heads at 9.8:1 compression ratio, hoping for 560@/530 ftlbs @ 6500 rpm
A 427 l88 factory motor made right around 540 hp and was rated at 435! The 68 vette l88 would run 10.80 with slicks and headers
My cousin had a '69 L72 with 4 speed. It was a beast and you had to be careful, it would put ya in the weeds in a heartbeat. Don't know what happened to it after he sold it.
When Nick was asking I said it better make at least 550 HP with those components. I think it's capable of 575 give or take a little. Water leak is when I commented.
I bet if you put a single plane on it it would pick up 10 to 15 horsepower I know it's not as good on the street cuz he wants low-end torque but if he was full out racing I would definitely run a single plane. Definitely good numbers for 4/27 always love Nick's garage
I think a 1 1/2” spacer would pick it up 10 to 15hp.
Chevy fan here, thanks Nick. All your content is great.
Awesome! Thank you!
Hi guys, that looks like valve float at 6400. It needs a stiffer spring to go past there. Nice engine. I’d love to have any of these engines you put together. So fun to watch. Let’s make some noise.
Maxed out on valve springs with hydraulic lifters.
@@nickpanaritis4122 oh ok. Then set the rev limiter to like 6200-6300 and be happy with that. It’s a cruiser not a racer anyway.
@@realazliving ...L agree.
This is another fun video. I have wanted a 427 in a 1967 Corvette for 53 years !
Street cars don't spend a lot of time at 6500 RPM.
I want power and TORQUE down low where I'm actually using it.
I can't wait to see this in a car!
I'm glad to see you doing a video on Chevrolet do a few on small block 327s I would really appreciate it thank you and you're doing a great job keep them coming. ✌️
Nicks constant is 1.32 so 432 cubic inches x 1.32 = 570 . Most builders would love to be able to build engines and get the results that Nick gets, consistently!
Just buy good parts and you'll do fine! No magic to it, it's science!
Dana "60" Glass. Great dyno pulls on the 427. Love to see and hear a 375/396 and compare numbers. Great video as always
Needs ovate springs and titanium retainers. 800 cfm will feed it plenty.
Would also recommend 1.8 rocker arm ratio on the intake side of the valve length is long enough.
That should wake it up a bit more.
Great show Nick! You’ve got it all, from a great sounding 427 to awesome mail time!
Im a Mopar guy thru and thru but a high revving BBC is fantastic.
Love it. Oooooooooold Skooooolllll. No electronics. No Bullsheet. Just making ponies……!!!!
20:09 That's an odd drop off in power, likely the beginning of loss of valvetrain control. Those heads have a heavy intake valve, though not as bad as the factory 3/8" stem valve. I've witnessed severe valvetrain control loss, the graph falls straight down. This is just warning you it's not happy above 6400, and after listening to the owner wanting to spin it higher before this run, I would strongly suggest an ignition with a 6500 RPM limiter. Sweet graph with a very broad powerband.
I had good luck running Accel blueprint HEI distributors. Dial in the right curve and they were hard to beat for the money. That was back in the 90's though. I ran a Q- Jet as well.😁
Interesting when you pulled the cap on that distributor. Old school. No electronics. Cool!
George that was a great gift you got! That model car was perfect!
Yes it was!
Those valve covers are sick. Love the finish flags.
They are!
Beautiful sound I absolutely love hearing a 427 wide open
