Dyno: 10,000 RPM With A 297cid SBC! 

oh definitely, they change again at 11k into a scream. can't wait to get my dad's dz302 back on the road again with his 11.5k 302 (317 now technically)

Yes, they do sounds great at that point.

You don't know that!

Yes ten big kaboom follows over 9 grand on any push rod engine is death sentence fast

Yes they do ! The pro stock stuff regularly approaches 11000 rpm out of 500 cubic inches.

Liar.

@@lollipop84858 ahhaha

how did you made 11.000 in a v8 329?? engine machinist

@@termonostruman you use a 283 crankshaft and a 400 cubic inch block. And special main bearings. This makes a over square engine capable of very high rpm's and lots of high rpm power.

What would you say to dropping an EFI 327 into a C4 with a ZF 6 speed ?

except this is an old school conventional 2 valve OHV pushrod v8. dinosaur technology doing 10k RPM is very impressive

That's a midram, not cross plane

@@timtourt7548lmao!! He’s talking about the crankshaft orientation there, Turbo Tim, not the intake.

Yeah imagine on train peak hour 😅😅😅😅

The strangers genuinely won't care

This. Exactly this.

@@AeroSS87 That 500 would have a lower pitch , than this.

@@rader1175 kinda...but its at least 10-11k rpm

Agree , they all sound good ,but these little guys have that high pitch scream

Why?

It actually a common combination. Used by Bill Maropolise back in the day. Today better parts.

Rod to stroke ratio is the beginning

Based on the displacement, I'd assume a destroked 327.

It was common to racing culture "back in the day," but not so much street racers. Right after high school (1980) my friend built a 4 bolt 372 CSB with the same build as the 1/2 mile circle track cars were using that would run at 8, 000+ RPMs. My 396 CBB was built with the same theory (huge duration cams) using extra hard main bolts and would turn 7300 RPMs in the 1/4. Back then, I freaked out many people who wanted to run my 396 'boat anchor" against their small blocks. Once they heard that 7300 RPMs open up with a Cehvy Corvette tri-power intake on that intake ported 396, they would just shake their heads in disbelief. lol, good memories.

​@@AndrewDorsey27, More like a 283 crank in a 283 bored Block , The DZ 302 is a 283 crank in a 327 block . The 307 is a 327 crank in a 283 block . My small block 327 is pushing 600hp and screams to the moon at 11,000rpm before the valves start to float .

Was it a money shift

Oh your a 68 SS Rs Camaro man figures id like you I got my black one with a 302 dz high rev kit and a 4 plus one 12 bolt 308 gears straight pipes 3 inch out the back obnaculasly loud and proud it's a daily driver old school torque thrust d spokes 8 n a half on all 4 corners it's alot of fun these guys with 456 and big blocks I'm like let's go follow me

Let's go thru some curves you remember the penskie Camaro

But I got full Blk deluxe interior and a roll cage fact tack and gauges

If you see this tell me about yours I've done some cluster busting in my day I'm in ft Lauderdale I'm 61 had 68 s since I was 17 years old and I got 66 67 ss 396 Chevelle's and a 55 bel air hard top late 60s style 3 petals on all

Why?

With your phone connected to a really loud speaker lol.

​@@kargmeisterhell yeah

So what kind of rig did you put that motor in

Yeah up and down!

Lol try 18 to 20 grand old f1 motors and many bike engines. 10 grand is limit and short lufe of push rod junk. Real motors start making piwer at 10 grand. Domestic engines are shit. Hp per liter suck compared to real motors

​@@RT22-pb2pphey news flash formula one motors dont even come in a Bugatti🤷🤦🏼🤦🏼😆🤣the real car world doesn't ride around with engines that dont make power until 10,000 rpm this probly went in a gasser 57 Chevy and driven on the road. Not even Ferrari or Lamborghini have engines that come with real formula one engines that spin well above 10grand. Actually quite a few Italian sports like Lamborghini and Ferrari cars redline well under 10,000rpms🤷🤦🏼🤣

@@RT22-pb2pp A little reminder, the Small Block Chevy engine has won more races than all other brands combined, and still today winning more races than all other brands combined, the push rod design is the best design for larger ci engines, that is just the way it is pal.

@@user-Dr. never said it was not good engine for certain things but limit displacement like many race series and dohc that can rev to 15k and above os only wzy to make big power with small engines. Push rod needs size at rpm is limited dohc engines can make piwer with small displacement, so why are your feelings hurt just stating facts. Pushrods limited rpm ceiling so fpr power they need displacement or turbos or supercharger.

The smaller engines use sheer rpm instead of brute torque. I noticed that most 283 cars that go wheels up don't really carry it long. They pop up and right back down (usually). Still very impressive.

PROBALL 3 inch stroke

It would depend on the application. On a street to weekend warrior engine the cubic inches and extra stroke would work better. On an all out race engine it's possible that the 377 could work better depending on the tires, chassis setup etc. You are basically just keeping the piston speed within a certain range that will allow your rods to live. Shorter stroke cranks can turn more rpm while keeping the piston speeds down but again it's application driven. If you spend the Big $$$ required to make the 406 , 414, 421 etc motors turn high rpm and live they'll almost always make more power. Assuming of course you have a cylinder head capable of feeding the bigger motor the air it needs.

@@chriswhite8860 Thanks Chris for getting back to me yeah I have this whole 400 I wanna do something worth I just talk to a guy yesterday that said that old 400 blocks don’t like bigger strokes so I didn’t know what to do I see a lot of guys doing 377 and I seen that motor you got And I was wondering what crank you run in a motor like that I know the 377 is actually a smaller crank and the 375 that’s in these 400s So you’re saying that going with the bigger crank is better than going to a smaller one

@Awful Coffel’s One Car Garage what are you planning to put the motor in and what's your plans for it ? All out race engine, or race on the weekends and minimal street time, or will it be street only ? The reason I ask is the 400 blocks once you get over a certain power level can cause some issues. If it's just a pump gas street hot rod you'll be fine but for an all out race engine I'd put everything into a Dart shp block.

@@chriswhite8860 Gotcha hey thanks man yeah just gonna be a street machine motor probably

@Awful Coffel’s One Car Garage I would build what you have then. Keep the compression around 10.5 a good hydraulic roller cam A good set of heads for it (AFR 210 or Dart pro 1 cnc both work great out of the box just have someone check the valve jobs for runout and sealing) a performer rpm dual plane intake and a good carb you should be able to make good hp in the 500 to 550 range with a pretty mild build and you'll have gobs of torque. Good luck with your build man. Let me know how it turns out.

That's definitely getting it done !

Lots of video, no tach!

50lb steel flywheel. Much more kinetic energy when you drop the clutch.

But also have a big tire monza stick, mostly fiberglass 2100 lbs. with me. This engine would keep me busy !!

ya right. LOL

@@PerformanceEngines No answer, I use to drag race a bored out 283, we called it a 302, shift at between 10,000 and 10,500, fair question, that would be a 3 inch stroke, just in case you didn't know.

@tompeters5414 front cam driven distributor, it allows for more intake clearance.

10k

15 plus

Cam specs = huge X large. Bore & Stroke = small & smaller

$1.98 plus shipping and handling

This would have to be built for each individual that purchases one. Give us a call when you're ready!

@@Sdpartscenter thanks for your response.... I'm live in India and i love your channel ❤️❤️ one day I hope own this crate motor at my home 😁🤘🤘

Correct

NHRA classing

Big bore, short stroke. Slower piston speeds and great valve unshrouding.
