Re: engine decode suppose to be 327
Not a 327. The three character suffix identifies it as a 1970-up engine, and the T identifies it as a truck engine. There are two uses for the TKA suffix that I see:
TKA 1976 350 conv.cab L LS9 165 4 C-10 & 1500
TKA 1978 350 conv. cab, m/t L LS9 165 4 C-10 & 1500
The partial VIN is from a chevy (C) truck, 1978 (8) model year. I think the "S" is the Ramos Arizipe, Mexico plant, but I am not sure what that plant made in 1978.
