Muncie M22s went into production in 1967 and were mainly designed for road racing rather than for drag racing or street use. The straighter angle cut on the gears made for the winning noise and also made them harder to shift. The larger diameter internal pins, shafts and fine spline input shaft made the M22 more durable than the M21 and M20. Swapping an M22 onto your Chevy required a change in clutch disc to a fine spline type and a larger diameter tail shaft yoke. This is a must, to fit. M21 and M20 can be swapped with no modifications required. Fact: A M20 was designed to shift smoother than a M22, was quieter, and had a more desirable 1rst gear ratio than the 'lazy' M22. Most cars with rear end gears ratios in the 3 series launched and revved better with a M20 than with a M22. The M22 required a stiffer rear gear ratio to make up for the lazy 2:20 gear ratio on the 1rst gear. All M22s came with a 2:20 first gear ratio. They were made and geared for road racing and definitely were stronger on withstanding more abuse and high torque and horsepower. While the winning of the gears was found to be appealing to some, it had no positive affect on shifting gears or low end performance. Such is the case on GM Hydro Turbo 400 automatic transmissions when compared to Turbo 350s.
@@josecortez5213 , you should try the New M-23 Muncie Rock Crusher , it has cryogenically hardened gears , It's in the $3000 dollar range , Sounds just like the M-22 but Better and Stronger , Can handle 700hp easy
As a middle schooler I had a neighbor named Butchie who had a Chevrolet 454 brand new red with black stripe. He'd creep up the street and we'd stop our street hockey game just to listen to this exact whine. Thanks for the memories...🤙😎✌
Thankfully, that lovely whine lives on in Tremec's line of TKO transmissions. More ratios, overdrive, and way stronger box to boot. Bought mine 14 years ago and have put 10's of thousands of trouble-free miles on it. Of course, back then they where only $800 instead of $2200 like today!
@@Loulovesspeed No, @ 124, that actually "is" the blinker flasher making that noise. I heard it too, and you can see the green indicator arrow flashing, as he is turning. But yeah, you also can hear the crisp snapping of the shifter, as he engages each gear too.
Smh man I remember hearing this in my dad's Z/28 when he used to take me to school lol and to me nothing beats that mechanical sound these transmissions make.
I was getting ready to type "Bring that thing outta the hole grandpa" when your message popped up on the screen that you were breaking in a fresh rebuild. 😄
My friend dropped a Rock Crusher into his 64' GTO. I loved that whine. Had a bad throw out bearing in it, and that rattle was cool too. I can still hear that sweet music, even today. RIP Oz.
I had a large block 66 GTO. Muncie Rock Crusher. Goats were heavy & boxy. It was a classic muscle machine. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MampOXnU7-c.html
Damn, I haven't heard that in decades. Its so sweet.My "66 Impala Super Sport had the same behind a 375/396. Love finding videos of this kind of stuff!
@phosgene11 I had a 1965 SS impala also with the 396/375 , no m-22 , but it did have a (if memory serves me ) 400 Turbo with a shift kit , 35-40 mph in drive it would bark the tires when shifting , I paid 895.00 off a Chevy dealership lot in 1973 , I shoulda kept it . Regards -Robert
I used to own a 71 SS 454 (LS-5) with the factory installed M22. That transmission really added to that car being unique. It was a smooth shifting transmission even with the factory shifter. Nice video!
That M-22 Rockcrusher was a Helluva nice transmission, I love the sound of that gear whine!!! I remember as a kid, I rode in a '69 GTO with that Rockcrusher, stuck with me eversince!!! That was 45 years ago, wow!!!
love love love it. Reminds me of a friend who took me for a ride when we had study hall in our senior year (1973) of HS in his 1970 Chevelle SS, we were allowed to leave school during study hall and the sounds of that magnificent powertrain were echoing off the stone wall along the street he did a few 0-90 mph runs. Makes the hair on the back of your neck stand up.
I always grew up a big 1970 chevelle nut, but I have to say 66-67 are my favorite. Love this car! Rock crusher trans, 396, convertible, perfection. Love the steering wheel view to go with the whine
I owned a 1970 SS Nova with a 427 and Muncie 22 and i missed that unique sound that these transmissions would exhibit, there is also an awesome feel as you go through the gears, one of pure power and muscle.
Yeah sure you did. I bet with two bottles of STP fuel conditioner and bumping the timing up two degrees it ran in the nines thru the mufflers right? Just by the way you frame your words, it's not hard to tell you are a bullshitter!
@@anthonynelson9136 Well yeah, for ONE....WHERE DID the big bad 427 come from for starters? Being it was a 1970 Nova SS?....... ALL the Novas (68-69,70 were 396 only) with the 70-72 Novas having the 454 BB mostly as well (with some 70 Novas carrying the 396.) But yeah....NO GM FACTORY fitted "SS Nova" EVER WAS, available outta the GM factory with a 427 BB motors...ONLY the obviously SUPER RARE, Nova COPOs and Yenkos COULD BE had with the mighty badazz 427 motors.....,😎
It's very refreshing to see someone shifting that beautiful machine gently and letting the synchros do their thing. Power shifting is fun and all, and when you're on the track, it's expected. But many folks fail to realize how hard it is on synchros (and forks in extreme cases!) GORGEOUS '66, by the way.
Thanks for the comment, Greg. I did a lot of racing on the street and drag strip in my younger years. I learned, that if you want to run hard, you'd better be able and willing to pay hard. I had just put this transmission together, so you are seeing it on its' maiden voyage with no miles on it. I have worked on these old cars all my life, and know it to be well worth it to be especially easy on it, as all of the parts are warming up and wearing in together. This transmission was an original 1968 model year M22. It sat under my workbench ever since I removed it from one of my cars in 1974, and had all of its' original factory gears and case intact. It just needed synchronizers and minor internals to be replaced and refurbished. It is very hard to find the original factory M22 gears and major parts nowadays for a reasonable price, so I am going to treat this transmission with respect. It may just be me, but I feel, that the whine of the original gears running in their original case sounds the best to me.
those replying not using a clutch should read your post.the autos with m22 came from factory with a clutch for a reason. i have shifted both ways in my younger years.nothing beats the sound of a m22.it makes its own music
This was my father's choice for drag racing. He had a 327 in it w/ that M22 transmission and I remember that whine as he accelerated/decelerated. Loved it when he would let me ride w/ him during a race. Such a thrill for a six year old boy. For my eighth birthday I asked him if he would teach me how to rebuild an engine by helping him rebuild that 327 down in our basement, during that winter. I'm currently working on the ever popular LS swap into my '02 Blazer. What a PITA this has been to attempt solo.
Sounds perfect, I had a 67 Chevelle SS with a 325HP 327 and an M22 that sounded just like yours, really brings back some great memories of some road trip in my Chevelle, thank you for posting!
ALL the 66-67 real deal "Super Sport" CHEVELLES were/had 396 BB motors in them from the GM factory. The 64-65 Chevelle SS cars were the ONLY 2 years that the actual Super Sport model would have 327 motors, and even some 64 SS CHEVELLES (Not completely sure about the 65 model) actually HAD the straight 6 motors as well! So you could order a 64 Chevelle AS an SS WITH the straight 6! Knew a kid that had one (and known of others) ... So, do you know IF/WAS your 67 Chevelle an original SS car and someone swapped out the original 396 in place of the 327? OR was it an actual 67 MALIBU (non SS) that originally came with the 327 SB 4 spd? (As THOSE were some screaming motors that COULD upset lotta BB Chevelles when setup/tuned right/OR even just straight outta the factory as well 😬) .... But yeah, ALL real deal Super Sport CHEVELLES had BB motors starting in 1966, WITH EXCEPTION for the super RARE 201 Z16 65 SS Chevelles that were fitted with the 396 BB. (that would become the norm for ALL SS CHEVELLES.) 😎👍
@@jamescon55 It was indeed a real SS 396/4 speed, it had a hard life getting wrecked, instead of fixing it the original owner sold the car to someone for the engine, the car minus the engine was passed around in the local area until a guy I knew (Kenny) ended up with it. Kenny had a low mileage one owner 65 Impala SS 327/4 speed that was riddled with rust so bad it was sagging in the middle. Kenny took the engine and trans from the impala and put it in the Chevelle, he did some other work to the car to get it going but it had a problem with it burning up the ignition points. I ended up with the car in a trade deal with Kenny convince he was somehow putting the points in wrong but the problem persisted. I had kept some old "Motors" manuals and a bit of research of the wiring harness revealed a "resistor wire" was feeding the positive side of the coil, sure enough, the guys that pulled the motor ripped the wire out, Kenny, unaware of the wire being special did what any of us would do and splice a piece of normal wire in it's place to get his engine running. Thinking a bit on how to fix this issue I decided to use a "Ford" coil after my research showed an internal resistor, I had considered a Mopar ceramic type but they fail too often for my taste so Ford coil it was, never had a problem after as I took that car all over the northeast listing to that Muncie music and the rumble of a pair of Hush/Thrush mufflers.
Love that gear whine! Honestly, I'm glad I didn't hear a bunch of high rpm shifting with the tires screaming and the transmission getting slammed from one gear to the next. It would have taken away from what I was trying to listen for. I don't mind the rest of the noises I mentioned, but time and place is all. Breaking in a new clutch is a good reason to make an enjoyable video, and this one is calming.
Thanks for this. My Second car 1970 nova SS had a M22. First time I drove it thought it sounded like a Divco Milk truck with that whine. Lot of memories. lot of tires🤑
Just like I recall.Great looking and fast cars these were,almost lost my life in a midnight blue hardtop ofone of these.Nice to see soeone keeping the faith on original detail.
Sounds good! I had a 67 GTO that I bought new. Kept it 43 years. It was an M-20. Loved the gear whine of that car. Wish I still had it. Drove my friend's 65 Corvette with M-22. Side pipes. It was loud....
Cracks me up! Everybody treats these cars like gems now a days. Im 58 yrs old. When we were kids we beat the snot outta these cars! Not knowing they would be gems later on in life! Lol!
@Michael Cuff truer words were never spoken , I’m 62 , I ran the absolute piss out of my 65 SS impala (396 /375 ) not to mention my 62 belair with the factory 348 , lost a rear end in that one , sad , the more you know
How true I'm 60 and drove the cars like stole them,my dad once said to me, you sure go through a lot of rear ends and trannies. My 2 favorite's 65 GTO tri power and a road runner, if only could kept them all. If only..
@@michaelhaynes1505 I hear ya Mike. Full throttle powershifts were the name of the game. Was disappointed in this video, cause of the wimpy driving. "Babying the M-22 cause of a fresh rebuild"? You gutta be kidding.
we were definitely rough on them. We had no inkling of just how unique that era of in car history would be at the time, and I suppose that's why these are so rare now: We USED them... hard.
Still have my 70 challenger 440 4sd Dana 60 . I've had it since 1974 ,the original motor is sitting over in the corner of the garage. I've got a stroked 426 in it now and I still drive it hard the way it was meant to be. I'm 62 years old and my grandkids think they should have it. I told them they have about as much of a chance of getting it as their dad did. They still haven't figured out what that means.
I have a 70 chevelle zz572/620 with a turbo 400 but now have decided to change it to a 4 speed with the M22.Thanks for the inspiration as I forgot how sweet that sounded in my other chevelle as a kid,ss454 Ls5 4 speed M22
I was thinking the same thing, but that’s how the cars were built at the time. You got used to it. I had a 69 Chevy stepside with a 468 that was like that. If I was racing, or driving in competition I would’ve changed to a different clutch. Some things IMO you just leave alone for casual driving.
Man, I love that whine. I've had 2 1971 Z28s with the M22. I just bought another 1971 Z28 and it's very low miles. The M22 feels so tight and new...it gets me very excited. Love the Chevelle...love that damn whine...
I had one in a 68 Firebird 400 H.O. I replaced the shift knob with the Hurst T-Handle, which was common in the mid 70's. Wish I had never sold that car.
SOUNDS SWEEEEET!! Shifts badazz..too i used to watch my dad shift the stick.. From the hump in the. Middle of the old school rides he had.. My favorite was my dads 72 chevy pick up with 454 stick shift..
This is my favorite Rockcrusher video. I want to convert my 70 ‘SS to a Muncie 4 speed. I’m sure it’s a nightmare of a job, but anything to hear that lovely whine!
I like your'66 and a real M22, is seems every time someone hears Muncie they call it a "Rock Crusher" without even knowing that it was only M22 not M21 not M20. Again great car ,I love seeing the old school built bowties and not the over restored BJ cars.
cool car ! I drove a m-22 for about 15 years in my 64 chevelle Malibu with 456 gear ( talk about whine ) no radio, 327 solid lifter isky cam ...in about 1996 I went to a Richmond T10 288 first gear now with 355 gear in the rear ...pretty much the same out of the hole and now better on the freeway ... hey the Richmond whines pretty good too ...love the Richmond T10 ...one day hopefully its going to get a 5 speed with OD ... my brothers got a 66. cool video
Mine was color blue for 1966 . With M/T five spoke mags 396 bored over change up on the cam heads port work . Went to a 4:11 gear funny thing it would eat a set of AC plugs up in a week or so . Had to go to autolight plugs never could figure out why . But those were the days . Lost her in a head on with a truck but we both walked away !!
Ive had 442s and camaros but my Subaru Sti 6 speed manual w hard mounts instead of bubble gum rubber does same noises just sayin, you can still get those school bus dump truck sounds from new cars that run 12s lol. Even Saleen does straight cut gears on Tesla Electric 2 speeds to 'wake' up the car
