Differences between 65 & 66 cars

[strictlypersonl]

The tail lights were changed from single rectangular to top round light/bottom reflector some time in the production process.

For the last time, the 427s in the 3200 series car were center oilers, not side oilers. I also doubt the idea that the 427 was an "option". When Shelby started slipping 428s in as an economy move, he was quite stealthy about the change.

1965 Cobras were the comp and S/C cars (CSX30xx)
1966 Cobras were the street cars. (CSX31xx, CSX32xx, and CSX33xx)
CSX3104 (early street car) built in Nov 1965 is titled as a 1966 Cobra.

In general

30xx series cars had 427 Side oilers
31xx series cars had 427 LR Center (or Top) oilers 2x4 intake manifold
32xx series cars had 428 engines 1x4 intake manifold
33xx series cars had 427 MR Side Oiler 1x4 intake manifold

I thought in a past discussed thread about the topic, that someone posted info from a late Cobra sales brochure that showed the engine upgrade option. I could be wrong.

Sal,
Before posting my question, I did a search on differences and drew a blank.

Can you give me a link to the previous thread or a key word that the search function would find it

thanks

Paul
