New Alan Colvin web site

Dear Mr colvin
I have what I believe to be a 1969 SS 396 chevelle. the car was built at the baltimore plant. at the bottom of the trim tag there is a line of numbers and letters. on 1 other board I was told that they were plant specific and offered NO info as to possible options that a car came with. I know that 66-67 they were option codes. thank you for any insight

I know Alan doesn't monitor this board, but I'll try to help.
The usage of the Fisher codes stopped in 67.
I think the code you are referring to is what is called the work order. It's a # like E123. It appears that the assembly plants that had multiple car lines used this code as an aid to schedule the cars.

Those #'s are DNP sequence codes, and are a one of a kind code for each car for the assembly line workers. They match the code in Box # 24 on the build sheet. Each plant had their own set of codes also, so it is very hard , to impossible to decode these #'s.

Have a question about the CPD engine code.
My '71 LS5 - with original motor - is a CPD engine code. T0810CPD. Has a T400 automatic as well. Build sheet verifies this that it is a 365hp and the motor that came with the car. I see that the only combination listed is a 4 speed car unless you had a Monte Carlo.


Is this an oversight on the website or am I reading something incorrectly?

The book lists the 454/365 TH400 engine with a CPD code for a 1971 Chevelle, Monte Carlo, and Passenger.
