1969 Nova Engine Code

[YENKO DEUCE REGISTRY]

I believe it should be 'JJ' for L89 and 'JH' for L78, the same as what is listed for the Camaro, (similar to the rear codes). The 396SHP codes are not model specific, just transmission specific, so there would not be a special code for an L89 'Nova' vs an L89 'Camaro'. Even if it was done as a COPO, the engine code would most likely still be 'JJ'. The '70 COPO LT1 Novas received engines coded as CTB and CTC representing the 360hp version of the LT1 installed in the Z28's.

We have discussed at length the possibility of an L89 Nova receiving the L78's 'JH' code. Most feel that would be illogical, especially for warranty purposes.

Thanks.

So the engine codes are not model specific. Therfore, it is possible to have a 69' Nova 396/375 A.H. with engine code Ke. As is the case for the 69' camaro w/ 396/375 A.H.

That is according to A. Colvin (Chevy by the numbers)

I quess I am a little confused with the engine codes. For example, (NOVA)- 396/375 (JH - SHP, 4-speed), (KC - 4 speed, SHP HD Clutch)

(Camaro)- 396/375 - (JJ 4-speed A.H. SHP) (KC- Manual, SHP, HD clutch) (KE - A.H., HD clutch)

You mentioned the Nova L89 with the code JJ. But this is listed as 69' Camaro.

Sorry to be a pain in the ....

Sorry 'bout that, I'm going from memory here and thought that the L89 code was 'JJ' - it might not be, but our belief is that an L89 Nova would have the same engine code as the L89 Camaro's.

We have heard a lot of stories of L89 Novas, but none have ever been verified with either a coded block, POP or paperwork. We believe that some were produced, just haven't found any - yet!

I checked the CRG site, thought I was going crazy!
