I UPLOADED THIS FOR MY DAD, I KNOW NOTHING ABOUT THE CAR. SORRY.
Engine ZL1 427 all aluminum, pro top line head, comp cam, 1000 cfm holley, 5 speed tremec, 411 gear.
TWO PULLS: 1st pull inconclusive. Tires spun on rollers. 2nd pull, tightened ties some more. Pull was better, but tires still spun (that's the blue smoke)
I guess stock poly glass doesn't work with all this power. Will try again with slicks on. - ยานยนต์และพาหนะ
Tightening the straps will mostly keep it from moving forward, stick large boy in back seat, then do a pull, plus, water dripping from car onto dyno doesn't help, and don't post a dyno run without any results!
Legendary car.
What a firebreather.
HOW CAN YOU HAVE A CHASSIS DYNO IN YOUR SHOP AND NOT KNOW THE BASICS OF RUNNING IT?!?!?!
To this day, still my all-time favorite Chevy engine. The ZL-1 427.
Mines the L78 that my 65 Vette had for 2 years and sold as a stupid youngster when I was 21 years old when the wire harness went bad.
1:30 just watch how the exhaust lifts the car from behind! 😮😮
Looked like the rack was wet. That doesn't help. Also, those OEM tires would be useless under those conditions. Really nice car!😮
this engine arguably is the most powerful engine from the muscle car era, 1964-1971 i know the 426 hemi, the 455 buick stage 1, The Corvette L88, which is very similar to the ZL1, The 1970 Chevelle 454 LS6, The 442 oldsmobile 455 W30, and the 1967 Corvette 427 tri power. with all of these cars i just mentioned the ZL1 in my opinion produces the most power. What do you guys think?
That's the best! The power of a big block and the weight of a small block!
This is the car that runs at Mid-Michigan Dragstrip. See at Cars and Zebras channel.
Badass 427! 1969 what a year for the Factory Muscle Car. Ford had the Boss and Mopar had the Hemi. Love them all.
Nice show of muscle ... in my opinion the ZL1 is the ultimate Chevy engine..
I'de say a 632 in. Is the ultimate big block, unless your taking about factory built.
That sound!
Goddamn, I think a little fluid just came out...
First one was delivered to Fred Gibb Chevy in Illinois on a cold morning. These care were for racing and chokes were not installed. In fact they came with the wrong sized carb a 780cfm instead of the 850 Holley cfm. Apparently Holley had a shortage of 850s that year. The right carbs were sent later. With no choke and it very cold it almost did not start to pull off the trailer. Two ZL1 Vetts were built but I don't remember where they were sent.
Ragin Reggin wow. How do you have this information? Also thank you for sharing it.

One of the Corvettes recently sold at the Sotheby's auction in Arizona for 3mil. A ZL-1 camaro like this one sold at Barrett-Jackson for $700k. I was there for that one.
nice car!
Pure power!!!
That smoke is coming out of the Exhaust. Not the tires rubbing.
one bad ass ride! i seem to have one just like it
Very nice
Yeah buddy smoked the tires on the rollers....haha yeah that's whats up
Plus or minus 500 h.p.
Those ZL1 cars pushed close to 600 rwhp
every singled ZL-1 engine outputted between 500 and 535hp. They never had a ZL-1 dyno under 500hp. They could do 600 at the crank with some minor headwork.
Inconclusive or lower than you are wanting to publish?
Nice, we watch the whole video for you to tell us the tests were inconclusive. Yep, that's what I would have done...
All natural horsepower; no turbos or superchargers needed!
Call me crazy, but older cars sound way better than modern cars.
That was before asshole politicians got in office and created the BS green movement.
That thing is vicious
Let a little air out of rear tires to prevent/reduce traction loss
I like the vanity plate, I know from experience it's very hard to get what you want because somebody else already thought of it, you better keep it or you'd lose it.
My brother still has his plate for his 69 Z that he got in 1973. It's plate number is Z-28, but it's on his 2014 Z-28 now and the 69 only gets about 150 miles a year on it now.
Can I have my click back, geeze
Blue smoke from the tires huh? What was all the smoke out the exhaust then?
I'm just curious which Genius figured it was prudent to put this ZL-1 up on the Dyno with arguably the worst tires in American muscle car history the F70 Polyglass....doing the grip work ?
Yeah, that doesn't make much sense.
is that the COMP zl1 cam?
I ain't saying this car isn't legit. But, I am saying that I must have seen around 85 '69 ZL-1 Camaros showcased in you tube vids, plus a few '68s and a '67 tossed in for fun.
They only made 69
@@jdog569Not only that, but they were not made in '67 or '68. You get the drift now?
@@bbb462cid ..you... you were lying.. everything you said was... . . UNTRUE?!
I've heard the ZL1 with 800 cfm Holley installed dyno'd at 487 hp, the L88 at 500. Super Chevy magazine from 70's.
That sounds about right? For cam, heads etc.
That would’ve been a Poor result for both of those engines, the l-88 should easily pull around 550 hp @ 6400 rpm, the Z L -1 a little more, the biggest difference, it was all aluminum.
I forgot to add that the L-88 & Z L-1 both peaked @ around 7000 rpm, so 550 @ 6400 is very conservative.
@@garywilson7992 The ZL-1 had a a bit more cam in it than the L-88 did. As part of the Zl-1 program, each ZL-1 engine was serialized, spent 1 hour of break in on an engine dyno, removed and taken to their "test Lab" where it was ran on a special test program where a serialized engine output sheet was generated. No ZL-1 made under 500 hp with the range being from 500hp to 535hp. Sustained rev redline was 7000rpm with the valvetrain allowing 7600rpm in a drag race situation. The 430hp was indeed the engine's output, though that power number occurred under 5000rpm, revving the beast over 6000rpm would deliver over 500hp.
@@hoghogwild I wasn’t referring to any of that, for what went on in the factory production test lab for each ZL1 built, which may have been the case. But the L-88 & ZL-1 I’m referring to, we’re not factory built crate delivered engines, they were built in a machine shop, the L-88 was built with special order parts, using an existing 427 4 bolt main block, the ZL-1 aluminum block and parts were all ordered. But since there are variables involved for how much horsepower an engine produces, and would also depend upon the degree of competent precision of the Machine shop and engine builder, as well as what main & rod bearings clearances were used, since engines built for racing competition aren’t generally needed to be broke in first, so to speak, unless it was left running on the dyno. The performance numbers I gave were based on both dyno tuned engines, and the L-88 cam was also used in the ZL-1. So I guess someone could say that they weren’t technically a factory built L-88 & ZL-1. But claiming that an L-88 developed only 430 hp, as I know it was, is a little disingenuous to say the least, when that rating was based on only around 5300 rpm, I’m not sure, but there was a reason for it.
Awesome car and great sound. Sure would have been nice to know what numbers it made.
Ikr. What's the point
If I remember correctly, the 1969 ZL1 made 500 or more horsepower. Some dude said it made 550, but Idk.
Guys that knew how to tune these big blocks coulda got 525 550 outta that car
@@generalpatton8468 The 1969 run of ZL-1 engines at Tonawanda running on Sunoco 260 gas never had one under 500hp, all of them ran between 500-536hp. Minor headwork would allow upwards of 600hp. Longtube headers and open exhaust are considered mandatory to reach these numbers. As delivered with Camaro BBC manifolds, power was about 275hp. Some of the ZL1 Camaros arrived with a set of headers in the truck.
Everybody gangster till the zl-1 goes on the dyno
Awesome car, holy grail engine for me, still wondering why the brake lights go on when he stomps it , especially on second run.
Panic....
What’s the numbers wtf
what did she dyno at
Aaahhh this video made me smile, god I love muscle
nice lincese plate 4 real !!
Watching this video was a total waste of time. *THUMBS DOWN ON IT!*
Do it over and tell us the HP
4 guys pushing down on the rear of the car, DUH!!!
Also change rear tires to DOT street radials and then you would have your numbers.
Street tires are fine for a chassis dyno! It’s the “technician” that is at fault here. Not running the car correctly. Didn’t strap it properly.

Would look better with a spoiler on the trunk.
Anyone with a fart can on their Honda needs to hear 3:20 to 3:30.
i see blue smoke from the exhaust... possibly fuel???
Why is it such a secret that I never get to see a true dino test result, even the readout was obscured on some of the videos
spray some belt dressing on the tires and rollers
Smoke was coming out of left Bank. I'd check that motor out before pulling that hard again.
Do you know how to use a dyno? Was it your first time trying? You couldn’t get a reading both times? It’s rear tires were spinning on the rollers means you need more strap-down leverage applied over it’s rear axle. Judging by the looks of things, it was in the 600hp vicinity. Ford, Plymouth, Chrysler, Dodge, Pontiac. Buick, & Olds all had 400hp+ models on the street. Were you able to dyno any of them successfully? Your day shift job might not be working out for you.
That's the reason why Chevy Under rated there Engines
so it's gotta be around 450 at the tires
Oh PLEASE!. Inconsistent results? What you really mean to say w/o saying it is that you did not get the results you wanted. Nice car, plenty of power, but?
First pull tires were WET..
Certain dynos won't work , had same issue with my chevelle.
I have a tremec 5 speed, its only got 3k miles amd it has shifting problems, Im having it fixed now. Of course its no longer under warranty. The place I bought it from said I must be shifting incorrectly. I wouldn't buy a Tremec again.
Well the DZ 302ci. made almost 500hp from factory..and I was Watching a show on COPO Camaro..they said that this engine made well over 600hp..And there we're other shows said the same thing...now I don't know how true it is..but I hope so
the l88 427 and zl1 427 would walk a sbc any day
500HP?WRONG! I owned one and dynoed it at 382HP (crank)
The dz 302 is said to be 260-290 hp stock... during the gm underratd days. but could do 465 with head work. Likely at 8000 + rpm. The 461 heads were great in the 60’s but things have evolved. I wonder what a dz 302 would do with 18 degree sb2 heads.....? 600 hp maybe
Right Meow! It wouldn't be a dz 302 it would be a built small block chevy
A 302 built to stock specs make ~335 with header 355ish just like the L76, the only difference was the stroke. Stroke has very little impact on HP alone what it does is increase the torque of an engine. Bore has the most influence on power. So the 4" bore motors will all peak about the same HP with all else being equal the only thing that will change is the rpm that peak happens at. Short stroke higher peak rpm, the DZ take 600 more revs to match the L76 and 1200 more than the LT1. The DZ made about 40lb-ft less than the L76 and about 50lb-ft less than the LT1. As far as street engines go the ranking would be LT1, L76 and then the DZ.
Not going to show the numbers ? I get it was inconclusive though. Would’ve been cool to see what it was making even with tires spinning lol.
Is this running spray?
No....don't need it....12.5 compression
put some vht on them tires
body gaps panel trunk and door fitment are terrible , that car looks like it got put together with Elmer's Glue
My dad built an engine as close to ZL1 specs in the early 90's for his 74 Camaro that car was friggin ridiculous you couldn't keep the rear tires from going up in smoke, car was parked in late 90's and sold in 2003 to a guy in Kitchener Ontario Canada I've often wondered if it's still around, it was dark green 74 LT with black interior and absolutely no options, 4 speed and a 3.73 posi only thing not original looking were the wheels I think they were Corvette wheels but not positive.
That is the aluminum moter 1969 427 hp
So this is a newer style LS motor like what all the C5 vette's camaros, etc, are running around with? Obviously the biggest engine is the 427 in the C6 z06 vette's from the factory. Sorry, I'm not up to date on all the old school muscle engines if they made ls7s back in the day. Those are nice numbers btw thanks for posting them. I agree with the no replacement for displacement until you bring boost into the picture. I just recently dyno tuned my thunderbird sc old technology 3.8 v6 with stock restrictive , bad designed heads on a mustang dyno. I made around 445rwhp, and in the same neighborhood of torque. Mine has a very streetable comp custom ground cam with .588 lift 224 @ .050 duration, 112 lobe separation. I'm just happy with how dependable it is, been together in that similar format for 3 years and I just drive it. I can rip into it and really have fun or take it on a 1000mile trip, play on the dragstrip and drive it home all while getting 25mpg. Nice job on the car, sounds like a beast and on all fairness I knew it made a decent amount of power by how fast it ripped through the dyno. Just hope you are happy with it. A lot of people think they have 800horsepower cars until the dyno crushes their dreams.
iliketowatchthis No if this were an original ZL-1 427 with all the original restrictive garbage on it they made around 500 flywheel hp. Now a really sharp tune and junk all that factory smog garbage this motor makes 560+ flywheel hp all day long! Those numbers in 69 were huge for that era just like the new Z06 today with 650hp. I'm an old school guy but I'd be an idiot if I didn't agree that the LS motors today stock smoke the old school stuff stock. I think it's safe to say the reason there aren't any big cubic inch motors anymore is that no matter what there's no way in hell you could get them to meet stupid ass gov't regulations for fuel mileage. I couldn't agree more that's when you introduce boost! It's crazy the power some people are getting out of these turbo'd cars. Just curious are you saying that your stock V6 thunderbird is making 445 rwhp...???
In 1969 Chevrolet made an variant of the 427 L88 which had an all-aluminum block as well as all-aluminum heads. This variant, known as the ZL-1, was developed primarily for Can-Am racing.... However, 69 of these engines became the power plant of 69 COPO (Central Office Production Order) Camaro's in 1969. Like the L88, the ZL-1 had high-flow open chamber aluminum heads and ran a cam which was even more "hot" than the cam in the L88. Unlike the L88, on the other hand, the ZL-1 ran at 12:1 compression. In 1969 the factory's gross horsepower rating was 430 horsepower (I would assume at the wheels). While there isn't a standard calculable percentage for power lost through the drive train, the average power loss through the typical RWD driveline is about 20% from the flywheel/crank. While it's not that trustworthy, factoring in the average power loss through the drivetrain (20%) the ZL-1 would have been making around 516 bhp.
+Alan Schulte L88 was iron block aluminum heads. Gross HP is from an engine dyno without accessories and open headers, on a chassis dyno the wheel HP was less than 300 for the L88 and LS6. Hot Rod tested stock examples of both.
GlassTopRX7
The LS6 of that time (1969-1970s) was a 454 [453.96] c.i. big block V8. The L88 was a 427 c.i. big block V8. It [the L88] was practically the same engine as the L71 with the exception of aluminum heads.... The only advantage that the L88 had over the L71 was a weight savings of around 75 lbs.
While the ZL-1 engine had physical specifications similar to those of the L88, it was cast entirely out of aluminum. This dropped the weight of a fully-optioned (or dressed) ZL-1 engine to roughly 575 lbs.
Now I would like to see the sources that you got your information on the dyno numbers for the L88 aluminum-head 427, LS6 454, and ZL-1 all-aluminum 427.... Because I don't accept information that's supported by "It's true because I said it is."
Alan Schulte
Read your original post you said the L88 was all aluminum. I think you just miss typed what you were thinking.
It wasn't hot rod it was Super Chevy that did the dyno pull it's was also the L72 not the L88. The L88 would have done better but not dramatically so.

blue smoke is not tire...
Blue is oil
That thing is ripping
Actually the blue smoke is oil. If the engine is cold comes from the piston rings
Is this a documented ZL1 or clone? Either way fucking bad ass
I'm a Chevy guy and the 302 did not make 500hp from the factory
Not even close, they made about 355, just like the L76 and LT1. Which should really be no surprise to anyone as the only significant difference was the stroke, the LT1's cam was slightly milder. The peak torque changes just as you would expect while the peak power scales with revs.
They only made 485hp in flate out T/A trim... Back in the day!!...
Guess the numbers weren`t favorable.
Inconclusive.. NOT. Bad ASS.
The test doesn't work for obvious reasons .....you can actually hear the tire squeal. Next time bring better tires on a day when it isn't raining.
( that`s the blue smoke )
pretty sure at 1:31, that it broke the dyno.
lol this ross guy cracks me up. wheres your car at? ill be more then happy to come pick it apart.
Post a video, be ready for comments, good and bad.
5 speed tremec? This must be a terrible clone attempt because it should have a Muncie M22. There's also no reason to have the Polyglas tires on there since it has the wrong carb, trans, and exhaust.
Actually a Muncie M21 or a 3 speed automatic were only available.
el 427 bloque grande podía girar a 7000rpm su peso es el de un 327pc y sus hp no son 430hp si no 560 hp hacia los 402 m entre 13.16 y 11.8 dependiendo de la relación del diferencial y su velocidad máxima entre los 200kph y los 320 kph también de la relación del diferencial
Se hicieron 69 pero a 50 les cambiaron el motor para poder venderse
Y se estima que 4 los hicieron autos dragsters
Ahora solo hay 15 originales con el motor zl1
I think this should have worked out fine ......... all you need to fix was the driver. Big Frady cat! This is a 427 ...... born to run and CAN take a little abuse. You can baby it up to 4 gear ...... but all you needed to do was bring it up to 5800 RPM and hold it for 2 minutes. Watch the oil pressure and engine temp ... if things start to get a little squirrely ...... then shut it down to an idle and let everything settle down.I have a 327 300 HP high compression fuele head SBC and I love to run it on the dyno. Runs like a champ, sounds great, and really screams. I've run it up to 7200 RPM a couple of times ....... BUT only for a couple of seconds ..... floating valves are a little scary!
get better rockers and springs shell hit 8k that 327
Duh, they haven't a clue.
a y su costo era unos 7000 dolares
Can't be a ZL1 if it has aftermarket heads ,cam, trans and carb.
all it needs is serial # plate
ZL Won
The tires spun instantly, no way you are gonna get a reading.
su velocidad real es de 320 kph
No dyno numbers because he was probably angry, was told it would make 600 rwhp and didn't even come close. That's why most of these old muscle videos don't show numbers. Still ran well, I'll bet it is a low 400rwhp which is still very fast.
I will say this and am more than happy to show the numbers from my LS7 454 that is all factory other than a comp solid roller cam spec'd at .255 050 duration with .652 lift and a holley hp 750 made 503 at the wheels. That's with a stock hi-rise intake and stock steel heads with 2.25 intake valves and no porting. Thats around 620ish at the flywheel not bad for mostly stock 50 year old components. Compression is 12:1 yes impractical on pump gas, other than E85 pain in the ass, but I feel that if I go with 10:5 comp and AFR 300 oval cnc heads with a vic jr intake and 950 hp holley this motor will make much more power than it did in present form. However, there is no replacement for displacement and the 565 bug is eating away......
Well, first off in the video description it says that they're running polyglas tires on his particular video. Polyglas tires are bias-belted tires... bias-belted tires have less rolling resistance but do no perform as well as a radial. Second, you can hear in the video (and read in the description) that the tires spun on the rollers. While somewhat uncommon, it is notable that when this was being filmed the vehicle was wet - and therefore there is a higher chance that the tires were wet or that the rollers were wet and possibly contributed to the tires spinning. Also, in 1969 a COPO/ZL-1 Camaro was rated at 430 whp. Finally, as far as videos not showing numbers you can see from this video certain tires can cause inconclusive results.
+Alan Schulte There's many videos from the Pure Stock drag races of ZL1 Camaro's and L88 Vette's running in the 11's all day long in bone stock form. Very few production cars today run those times with much better technology.

"Conservative power ratings for the ZL1 were averaged at 525 horsepower. Installing a set of tube headers helped the peak number grow closer to 600 horsepower,"

If it’s a authorized chevy zl1 block and has the New zl1 heads and or old which is the chevy heads and numbers cam 886 pistons and or the new pistons that comes with the zl1 crate engine then that’s what it is if you know your engines Zl1 stands for aluminum block if you have the correct casting number in the block 3946053 then its official it is what it is a Zl1 block as I have one yes I have a zl1 using all the 69 numbers parts from heads to pan and the block is serial numbered as I have the specs sheet so know what you are stating he might not have one of the original 69 made but it is what it is don’t hate
