68 Engine Code

[Nova Research Project]

HawaiianCamaro;

I will give it a shot. DS is a 1968 Chevrolet (Full Size) 307 200hp Engine. It is shown in the Turbo Hydramatic column. The problem is that it does not specify TH 350 or TH 400. It could be either. Since it is a 307 I would guess that it is just a TH 350.

However, the Tranny code looks like a TH 400 code.
68 D 313 or
68 = 1968
(C)D = 327, 350, 400, 402 (the C is sometimes left off)
313 = Friday November 8, 1968

CM would be a TH400 with 307.

I do not have CBTN here this is just from my notes. Anyone else? I do not have a listing for CI.
