1966 Corvette 427 & M22 Trans

[firstgenaddict]

Weren't the 66 L72 M22 cars the forerunners to the L88's?
Yenko raced a 66 L72 M22... didn't he?

"...I still have nightmares now over some..."

Me too Joe!.

As I've mentioned before, I was working at the boneyard in the late 70's/early 80's when the 'glory years' cars were rolling through..

I used to put off squeezing certain cars hoping someone would show up who cared...caught a lot of grief from the owner and co-workers always poking fun at me about it too!.

Sadly few who cared ever showed up and the cars all eventually had to go..
So besides the flocks of Mustangs (all Fords were first into the press), I pushed tons of Muscle Mopars, GM's and other great ones into their final ride!.

There's lots I'll always remember putting in the press but specific cars I often think of are the '69 Judge coupe, '68 Impala SS ragtop six banger, '63 Nova SS Ragtop, '64 Acadian Invader Post, 70-1/2 Falcon Post...even a 'never built' Oshawa MK1V Chevy powered '70 Goat!.

I also used to save the best of the complete front clips, fenders and bumpers also every single factory performance hood and had them laying comfortably on their sides in racks.. I went back years later and the then owner nut told me he made a fortune in weight from the hoods alone!.

I tried!.

Sorry for the hijack/rant...back to the subject and James mention of Yenko's '66 racer, I'm pretty sure Yenko had one of the real '66 L-88 cars, yes a '66 L-88...like Penske got!.

Depending on the casting numbers, the heads might be worth the asking price of the engine. I would buy it and then ask questions later.

Aloha guys I need some help buying an engine & transmission out of a 1966 Corvette.1st is the price,The guy wants $3500 for the engine, pan to heads.He said that it is a 425 horse engine with rectangle port heads.What are the letter codes to look for on the engine block.Next is he said he also has the M22 from it & said he wants $1500.First question,On the trans is does it have the C designation on it, if not how do you tell if it is a M22.Also is the pricing for both in the ball park & also I would like a M22 That makes the loud noise.I know this one has the small output shaft,But does it make as much noise as the 1970 M22 with the large output shaft.My friend had one & it was very loud .Any help would be greatly appreciated Mahalo Irvin

Hello Irvin,
The 1966 M-22 Transmission input clutch shaft has no circlar grooves. The main case has 2 plugs in the passenger side in upper is the fill plug and the lower is the drain plug.
You need to get information of the stamping of assembly date and VIN stamped on the rear flange of the main case.
You need to get digital photos of the engine pad and casting part number and casting date. The photos of the transmission as described above.
This will help to see what are looking to purchase.
Regards,
Drew Papsun

Hi Drew:
I would use the muncie M22 two groove and dual plug check as a guide only. I got burned real bad years back on so called 66 M22 that was not. The only way to know for sure is to take the side cover off and look at the gear angle.Some replacement over the counter shafts had no grooves only and some m21's had the dual plug. Also at least up here 66 was a year they were not consistant in stamping the cases with any VIN.If he would post the casting numbers of the case and side cover and indicate if the side cover have studs for the levers which it should that would help along with a picture of the gears.
If that is not true CRASH correct me.
I have a real nice 66 trans no groove 10 spline input,small output, reverse switch and dual plugs but it has no M22 gears in it. Unfortunately I paid M22 prices for it but that was many years ago. Not that I am any smarter now
Just trying to help

There was a brown or maroon mid-year Vette under a tarp near Tripler hospital a few years ago. Has been there quite a while (10 years or more). Knocked on the door and the lady said it was her son's car and he was going to restore it. Couldn't see much under the tarp, but I belive it was a '65 or '66 if I recall correctly. Might be worth checking out.

There were only 22 (I think) '66 Vettes built originally with L72's and 4speeds. Check for a vin. A 425hp car will have a vin after 3,000ish +/-. "IP" is the engine pad code for a L72 in a '66 Vette. Prices seem fair but I'm not expert!

I believe the engine code is IK for a '66 vette that was equipped with the M22

Wow didnt know how rare these cars were.I was just going to put the drivetrain in my Camaro.I will ask the guy if he still has the car.Also sorry if my question was not clear on the transmission.I was just saying in reference to it might having a designation letter C as the 69'S had.I would not know how else to determine if it was a M22 or not.Thanks for all the response & help I will let everyone know the outcome Mahalo Irvin

If this turns out to be a '66 427 and you buy to re-sell, please PM me with the details. I'd be interested depending on dates.

Thanks
