I can hear my dad in the back of my head talk'n about his old 327 350hp 62 vette, dump'n the clutch at 7k or somethin like that... lol.... good stuff boys!
It made more than 100hp per liter, that's actually very impressive for an engine architecture from the mid 50s!
Anything’s possible with todays technology in camshafts and cylinder heads. No need for big cubic inches anymore.
@@123nova87 I still have a soft spot for the big blocks tbh
Lol who needs OHC with modern technology anymore?
@@bigboreracing356 I am interested into a 502 HO and throwing a couple snails at it. Mild cam makes it drivable and torquey down low while the boost helps it breath in the upper range. But i definitely dig what you did.
@@bigboreracing356 If this engine did not have valve floating pushrods it would be double the hp🤣🤣🤣
I bought a ‘62 327 block and crank today. All standard. I now know exactly how I’m going to build it. Thanks, Engine Masters!
Corvette builder on TH-cam built a 327 that pulls past 8000RPM and makes 505hp!!!!!
I love the energy of Freiburger
Perfect presentor.
Uncle Tony is better
@@Shade_tree_garage01 lol
Smidgen that garbage 🗑️ he reckons 😂
Dultch’s onair has improved 100% he was stiff as a old piece of drift wood when he first started watching him was painful lol 😆
The first engine I built was a 331 in 1981. I used a 4 bolt 350 block with a forged 327 crank and stock rods. It saw 7,000 many times, but usually by accident. The heads were unported 1.94 valve double-hump fuelies with a comp cams 280 magnum. It seemed fast at the time but was probably not much over 300 hp. Fun for delivering pizzas though..
Loved that comp cam 280 ...480 lift if I remember right ...nice sound.
It was my first sbc build .
Built a 331ci using a 350ci..... yea... okay loser 😂😂😂
What car was it in?
A 71 camaro with a saginaw 4 speed and 3.73 12 bolt posi.@@jblack5323

Please start send all episodes here on youtube instead so we in EU can watch it!!! I love this show and it was always on when i was in the garage!! Love what you guys doing❤
327's are magic. If nothing else, they atleast bring a smile to everyones face.
My question to Dulcich would be: Can you mod a Mopar 318 to get up ther at 8k?
I say the 383 is magic.
I'd say it's nostalgia for the boomer generation rather than magic.
Why build a 327 that revs to 8k when you can build a 372, 383 or 400 that does the same? So much have changed in terms of cams, lifters, heads, intakes and so on, so what is the point? Sure if revs are what you are into, why not take something that small to 9.5k?
@@AB-80X Their stroke length gives a very particular sound that the other engines dont duplicate.
@@AB-80X Even with modern technology, you'll eventually struggle to feed the extra displacement with the constraints of the SBC cylinder head unless you go forced induction. When I see people building a SB 400 I always question why waste your time when a 396 will easily run circles around it? The 327 is the perfect small block. It's free revving, yet still makes decent torque and the SBC head design can feed it all of the air it needs.
Grumpy Jenkins would be proud of your effort!
All you need is a steel forged 283 crank. My 68 Z28 had the 302. It was a 327 with the 283 crank. In 1975 we didn't have the tech available today, but I got 8500 RPM, making 550 HP. Selling that car was a life mistake I would like to take back
Have run basically the same combination with ported Victor jr 215's and ported Victor intake 11 to 1 compression and 1 7/8 headers for years in 71 chevelle, weighs 3200 runs high 10's on motor and low 10's with 150 shot. Turns 8000 rpm's all day, best little motor I have ever had and been together for 15 yrs.
You should start a journal would be cool
That's lightweight for a Chevelle! at least a 71 model I bet it sounds heavenly!
John sheets, she's gutted as much as possible. Just a fun little street car I've owned for 36 yrs. For what it is it sounds healthy, 670 solid roller.
What fuel?
@Robby robby oxygenated 116 is what it likes best, just for cruising usually a mix with pump gas but it will run on 93 just not very well.
Hearing a VTEC reference on Engine Masters warms the cockles of my heart…
I love how much fun you guys have! That added with the explanations and proof! Dyno time is awesome 👌
Wow! this was a hoot! one of your best ever videos, not a big fan of RPM goal motors but cant deny this one, it was fun! Thanks guys.
I could just listen to the sound of these dyno pulls all day long!
type in 297cu. in. 10,000 rpm Racemasters Comp. elim. eng. awesome !!
It’s a lotta fun watching you guys have fun. Another great video fellas.
By far the best combo ever tested on engine masters Bang for your buck horse horsepower and torque per cubic inch that combo is an absolute winner hands down no doubt about it
Is it? Respectfully, I've watched a lot of these episodes on MT, and I'm pretty sure they've done low buck LS engines (blown and NA) that surpassed this and I'm sure cost less money than the mega bucks 2nd setup they tested.
@@blautens
right?
The final setup is apparently 3k+ in heads and intake manifold, not to mention the 950 carb and cam. Plus all the hours on the dyno..
bang for the buck? they have 10K into that sbc...
two of my 3 fav numbers, 327/427
It sure exceeded my expectations. Those final tweaks were legit.
Freiberger, Dulcich and Brule--they just get better and better.
Great video. Awesome job on explaining it. Keep up the great work. Keep safe.
That is a killer combo to make that kind of hp out of a 331 cubic inch motor.
love watching this stuff I'm not a Chevy guy like to see more Mopar and Ford stuff but I'll take it love RPM I love Steve's mullet too 😁
Skullet.
@@CarsandCats he just want to watch the guys clean an engine out of the dyno room with dustpans lol
Mopar doesn’t rev like Chevy unless you have deep pockets.
If you love high RPMS check out the overhead cam engines that rev to 20k RPM.
Can't do that with dodge and ford.they blow up.lol
This reminds me of the old factory modified class, they came off the line at 9k and ran 8 seconds with 283-300 cu inch engines
Great stuff for the old guys. Much appreciated.
Always the best love you guys! Keep On Rocking
That is unbelieveable, thanks guys
It was beautiful music coming from that 331. I can see that in a gen 3 Camaro pulling down the back straight on Road Atlanta.
Freakin goosebumps I tell ya
Not bad for a pump gas street piece --
what would happen if you raised the comp ratio, put on a tunnel ram and 2 carbs like we used to do back in the day - remember the old Chevy pro-stock Vegas with 331 engines AKA Grump's Toys -- The claim back then was 750 @ 9200 with iron heads
You guys are definitely geniuses in your own right. I absolutely love the videos. Keep up the great work. 👍
Oookay. I think that is definitely a stretch.
On so many occasions, Freiburger has his stuff wrong, and frankly, why is he even talking? He is the one that knows the least, by far, and yet he constantly flaps his jaw. I guess the old adage of "empty cans rattle the most" is true in this case.
I'd much rather hear what Brulé has to say.
love this real engine stuff
My FAVORITE episode ever.
Love watching y’all push these motors to the limit! Keep up the good work!
Pushrods are made for low rpm trash trailer pulling, not high rpms.
Love them 327,s man.....still run 2 in my cars.....tough ol engines and nothing like the sound when you wined them out,Thanks for the video.
IMHO, the 283 and 327 were probably the best V8 engines GM ever built. They don't have the power of the LS engines, but can be built reliably to achieve the LS power levels. World Products makes a traditional SBC block that has the LS head bolt pattern cast on the deck surface, instead of the traditional SBC bolt pattern. IMHO, this is an awesome way to go.......
@@milojanis4901a Corvette builder here on TH-cam built a 327 that revs past 8000rpm and makes 505hp!!!!
what a cool episode. first motor i built was a 355 sbc that wasn’t much of a hitter, 400ish hp, but was great for cruising and here and there fun. currently building a 396 sbc, north of 600hp, and seeing a little 327 scream it’s way up to 550 hp at 8000 rpm makes me want to choose one for my next build. seems like so much fun
This is sick. Love these!
Love this build! Incredible sbc budget rev machine!
Id love to see the dyno pull of this engine starting from 2K, it would be cool to see what it is like to live with this motor instead of date it.
An engine like this would be paired with a 4000 rpm stall converter
@@andy2108 Yea, I know what it would be done for the strip. I would still like to see more of the bottom end and know what it does when it's out of the power band.
There's nothing wrong with showing a deeper dyno pull, even if it produces weak numbers down low.
why obfuscate or hide it?
@@andy2108 at least! was thinking 5000 stall, myself.
Lol id have a 5500-6k stall behind this engine. It would literally never see 2k . Maybe 1100 while its idling.
You know what would be nice? If pwople would think before they post.
Here's a question. Exactly what do you think would happen if you were driving at say 45 mph, at 2000 rpm and floor it? Will it stay at that rpm trying to lug itself up, or would it, as is always the case, kick down and flair straight up to 4500 rpm and run? Why is it so hard for people to understand that you don't run your engine at WOT @ 2000 rpm? I mean, are you going to use it to two a powerboat up through the Ike with a one speed gearbox?
What this does at part throttle at 2000 rpm has nothing to do with what it would do at 2000 rpm on a dyno during a WOT pull.
As for how easy it is to live with? If it's a manual with a highway gear, it will suck. If it's an automatic with a loose converter that has a lockup, then you're pretty good to go no matter the gear, unless you run some kind of 2.42 gear.
In short, you're asking a pointless question because you will never run WOT at 2000 rpm, and because why would you build a 331 that revs to 8k if it should be easy to live with?
Can't help but to wonder if you actually even wrench or race. Sorry, this is just so odd of a thing that most racers and wrenches would know.
Engine master my favorite series.
I love that combo on a small cubic in small block good job guys
Another awesome video. I love this stuff 👍👍
I've been looking for videos on Schneider for the longest. I just recently put 1 of there cams in my motor, can't wait to send it
Frieburger, I have never seen your hands so clean LOL
built an LT1 Chev Phase II Steel Bow ties, 2.05/1.60 with a .488/.510 Cam Perf RPM Intake, 1.65 Roller Tip Rockers dual springs w/dampers, 70 Corv Flat top 3.4cc pistons, valve float at 7200, would take it to 6800 1st gear Turbo 350, 2.73r in a 77 Monte topped out 4200 in 3rd doing about 135mph. I miss her
great Episode guys !!
Dangg what a great episode! More please!
Excellent! You guys are doing america a favor! We are proud of you all! Thank you!
This was a great episode, I would like to see this taken further, with lighten rotating assembly, lightweight valves and springs, and a few other tricks not often shown for 620hp
Nice job guys !!!! 😎
Awesome episode!
Great episode, I can see why reving small blocks to the moon is a buzz
so glad this is on amazon !
I love it ..... and I do remember 327's , the engine that revved !!!! Many Thanks.
This video is a winner !
You guys are geniuses
Nice combo I like it.
Love the 327 at full song! That thing sounds angry!
Y'all really want to make some power call, David Vizard that man knows his stuff!!! 😎
Many say the 1962 to 68 Chevy 327 is the ultimate motor, who are we to dispute that with these numbers. Makes me proud to know I have one in my daily driver.
And it's a TWO BOLT MAIN ! Now you understand WHY I built and installed my last 327 in my 70 Chevelle 4 door daily driver and not my 1970 LT-1. The 327 proves again it IS the ultimate SBC.
Brulee is channeling his inner Riff Raff with that hair
Organise so we can watch in Australia again.
I really miss this stuff.
Nice to see Steve's dentures finally settling in..
Ten years ago I bought a '69 Chevy C10 that barely ran, for about $500. When I took the valve covers off I found a broken pushrod, and RHS in big letters on the cylinder heads. I replaced the cam/lifters/pushrods with Comp pieces and I drove it until two years ago. I regularly shifted the 358ci at 6500rpm, but there were a few times I missed shifts and zinged it to 7500rpm. The person that built that smallblock knew what they were doing. Eventually the engine started burning too much oil(years of abuse and cam lobe metal from ten years before) so I pulled it and am now swapping in a 5.3 ls. The 350 is in my garage awaiting a rebuild to swap into my '82 Scottsdale shortbed 4x4
Bookmarked the video. I would do the same combo with race gas only and some more CR! Thanks engine masters@!
Lots of power in a tiny engine!
Love the Crypt Keeper hair on Steve Brule. Mad scientist look is fitting.
Now we're talking! Love that rpm. Now we need a big block with a huge bore like 4.5+ and 3.25 stroke.
This episode was sweet. I just can't wait to see some 18, 15, even 11 degree sbc combos compared to a 23 degree.
Your first engine analysis you said the valve train was faltering at 6,200 RPM. When in actuality you were pointing at 6,900 RPM. That was a great combination, especially for a dual plane…
Your video makes it plain as day that more cubic inches makes a cam act smaller. My 10.7 to 1 399ci sbc with 260/266@50 679/668 110/ makes 641hp@6400 and 560ft lbs.@5600 on 89 pump gas with 261cc 17* Brodix C-Series heads. Excellent video.
Impressive how you basically erased all of the torque loss whilst making 100 hp more. Very nice
They didn't erase torque. They lost 2 lb-ft while raising the remaining of useful torque, and gained 105 hp. This engine would be perfect for a high rpm stall.
Very nice video :)
I loved my 327, miss thoes days.
We need the dyno room banter even on youtube!
Thata lot of timing! big pistons make a flame front have a long way to go.
Engine masters are the best. Love these guys. They get right to the meat and potatoes
That sweet NASCAR sound, just perfect.
I love these guys
Love to hear the sing!
I was doing it with some 304 AMC , I was reducing the stroke , aluminum racing rod , original head because they already have the big valves big exhaust port with the dog leg port so I just got to open it a litle bit on intake and exhaust, custom made exhaust manifold and intake manifold, 850 cam carb …
Schnider has some good cams!!!
God I love this show!
I think Steve may remember the 2008 EMC when Dave Storlien showed up with a 331 SBC built with Junk yard parts. Hand ported 461X heads that had 167cc In. ports, No fancy aftermarket heads and a flat tappet cam. It made 450 Tq @4200 and 470 Hp @ 6500. That engine still holds the record for a 2 valve engine of the best spread between peak Tq and peak Hp in the history of the EMC. That same year Randy Malik entered a 331 sbc also, it made 444Tq @ 5200 and 507Hp @ 6500.
Lol a modern v6 makes more than that🤣🤣🤣🤣
@@fish_R_stinky69 Yes they do with 10psi of boost
AND with TONS more technology.
@@hybridssuck Yes I am not scared of technology.
@@hybridssuck If you hate technology why don't you just drive a 1922 Ford?
The actually an awesome cam
I set up a stock bottom 1972 350 chev for some rpms, thats a valve spring upgrade on some 1.94 heads, cam and intake. That thing ran 7200 for yrs racing at local strip, all for less than $600
My built 327 was very close to that. Shifted it at 8200 when I wanted to and never had an issue. Twisted my 68 Chevelle tho and I sold it when I got a cherry 70 Monte Carlo. I miss them both...
Thank you for sharing. Just another day in the office. FAN-tastic.
Pretty Cool. Would be fun in a light stick car
Awesome 🙂
i wouldve liked to hear a clip of them at idle for a few seconds....prior to the full throttle.......
I’m building a hi rpm “292” sbc with ultra lite h beam rods, steel 283 crank , loose clearances , .125 dome , etc topped off with a SY-1 Smokey Ram .
I think the 327 has the best bore to stroke to rod length (stock) combination of all the small block chevy's.
At first I scoffed at this comment, but then I realized it is actually correct. It has the solid 4" bore that is the golden standard of the SBC but it had a stroke between the 302 and 350. So yeah true. I might suggest the 377 out of a 400 block with a 350 crank as a close contender (though not a factory combination)
Stroke/Rod Length ratio does not affect the power output at all. ALL the top motor builders have said for decades to use the biggest bore the architecture allows, put the crank stroke in needed to make the displacement goal & then put the rod length needed to connect the crank & piston, although longer rods cause less angularity & more piston "dwell" time at the top making the engine slightly less timing sensitive, as well as having a lighter weight piston. I run 6" rods in my 3.75" stroke 409SBC street motor(and the wrist pin is still well below the oil ring) mostly because there was a much greater choice of pistons for the 6" rod than a 5.7".
Love it. :)
Not a bad little engine.
Brule's mullet sheesh
0:14 🤣😂🤣 you're right on the money with that comment. My eyes got real wide when u said 8000 rpm followed by 327
Awesome hp for such small cubic inches.
Oil Supply and Windage control for high revving motors. John Lingenfelter back in the 90's spoke about this long before You tube. Can you possibly speak on what you have done on your builds for both the Early SBC and the LS's to survive at these levels?
Can you build gen III 6.0 with a 4.8 crank and everything else needed? Would love to see something like that. Thanks.
All it needed was THE SALAD BOWL 😂
Ohhh baby that sings
