Turbo 400 and L88

[jbclassics]

The information I have looked up shows that 1967 was the first year the L88 427 was put in a Corvette..is this true?
Also was a Turbo 400 available in a 1967 Corvette with a L88 427.

Below are the codes off the tag of a Turbo 400 I currently have in my 1969 Nova 502, a past owner of the transmission claims that it came out of a 1967 Corvette L88...any help would be appreciated.

372

CD67- 35378

[COPO]

I believe 1st time an auto was available behind a solid lifter BB engine was in the 68 Gibb/COPO Novas in 69 it became an RPO for the Chevy line.

1967 was the first year for the L88 engine as an RPO. 20 units were built with this option that year.

I agree 1967 was the first year for a L88 Corvette, however I always thought they were backed up by 4 speeds....as in COPO's post. I'm not losing sleep over this but it would be interesting if it was one of the twenty or perhaps put in a 1968 /ubbthreads/images/icons/smile.gif

The best I could ever do with the numbers was...
CD=Chevrolet Division 400 cu in Chevelle or Monte Carlo
67=1967
35378=I assume a vin #
372= Date Code ?????

I believe 1967 was the first year for the L88 Corvette,but I'm no Corvette expert.According to my books,it was only available with the man.Trans,not a Th400.*Your Trans tag says it was assembled on the 372nd day of 1967,thus 7 days more into the following year.*35378 is the Serial number of the Trans.,not a VIN#. *The Letter code D is a 327 engine application.Only the Larger Passenger Cars got this trans. with a 327 in 67.I.E. Impala.

The turbo 400 would not fit in the transmission tunnel of the 67 Corvette without some modification to the fiberglass. Because of this, all 67 Corvettes were 4-speed or powerglide cars. All L88's for 67 and 68 were 4-speed. In 69 they mated the turbo 400 to the L88.

Thank you for the info I guess I can put that story to rest. It is however a great trans behind the 502 I have
had it upgraded with heavy duty parts a shift kit and a custom 2800 stall converter. The Nova however has the appearance of a COPO car very plain very factory.

'CD' is indeed a TH400 for an Impala with a 327 small block, I happen to have one tucked under workbench - the 327 too, couldn't pass up the pair for $100 at the local junkyard, all I had to do was disconnect it from the car /ubbthreads/images/icons/grin.gif

Everyone seems to be on the money with the code of this TH400, I have found it to be applicable to a Camaro or Chevelle not a Impala. But that could be the same code for those three cars. I have a 69 L-78 SS Camaro equipped from the factory with a TH 400 transmission, and this was the first year you could RPO a TH 400 behind a solid lifter big block equipped car. "CX" code wopuld be for a ,L-78,L-89,L-72, and ZL-1 equipped Chevelle or Camaro or Nova. A "CY" TH400 would be the code for a 69 Corvette. These transmissions are VERY rare and hard to find, and they have external differences in the casing as well as some internal heavy duty part applications. Send me an e-mail and I will send you pictures of a CX showing some of the part differences...............Joel

Joel,
CX was also available in the L-72 Impala. It was the guys on this site that confirmed a '69 L-72 convert I came across a year ago with that trans.

I would be very interested in seeing pictures of the differences if you can provide them via e-mail. Please see my profile for the address. THANKS!

Hi Joel,

I was reading through some old posts and came across this discussion on Turbo 400's with solid lifter big block cars. I sold a 69 L-89 Corvette with the Turbo 400 "CY" a few years ago and I've regretted it since. This combination was tremendous and the car was extremely quick even as I had the car bone stock. I'm very interested in getting one of these transmissions again. Could I please get you to send me the pictures of the differences in the "CY/CX's" versuses the standard Turbo 400's. My e-mail address is in my profile. Thanks a lot.
Regards,
Kevin C.

Rick,

I was under the #49 car just last week and the cases are different than my "CY". I was surprised to find that myself. I was mostly interested in the tag and the numbers so I don't know if the photos will show much of the case. I'll bring them with me this week-end. I have plenty of shots for my "CY", but you probably have all you need of those. /ubbthreads/images/graemlins/tongue.gif
