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

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!

There were 5,258 L72 Vettes in '66, only 15 cars out of total production had the M22. If it is a real '66 L72 than 3500 for a complete engine is a good buy. I certainly hope it isn't an orginal big block car much less an original big block M22 car and the guy is selling the engine out of it, if so he should use the money to have his head examined!

Good luck!

I have sold a bare 66 Vette 4 bolt 427 block for more than he is asking. It is a steal at the prices quoted and if that M22 is a real 66 I would be posting the numbers to try to get the drive train back with the original car since it is a rare rare combinations as the guys state.

I knew I was off... Always get the 22 production number figure confused with tranny... whopps.

...wouldn't the "C" designation he mentioned indicate the trans is at the earliest from 1969?...

Agree if it case is original but you know the way we all did in those cases back in the day and exchanged them for what ever we could find to fit.A true 66 M22 is a super rare piece. Be interesting to see what it had for a side cover and some of the casting numbers. That would help. Small output shaft is worth digging deeper.

The odds Andy of that vette still being alive some where is good. I know back in the day not even you and I were cutting up 66 corvettes like we did with so many others. DAAAAAAAAAAA. I still have nightmares now over some.

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
