1967 Chevelle SS 396 375HP?

[Z28DL]

Hi Bill,
We must have the same 66 Chevelle expert. My sources show there were 3099 L78 66 Chevelles and 612 L78 Chevelles built. I have a 66 L78 Chevelle with POP, titles/owner history and inspected/documented by my friend who is considered one of the formost authorities on 66 Chevelles.

My source says exactly the same thing...3099 in 66, which includes the ElCamino. So it looks like I was wrong...yet again Why the big drop in production from 66 to 67, I don't know

Yes, I'm pretty sure we have the same source/friend, Dave

The L78 was removed as an option for the Chevelle in 1967 and then reintroduced later in the year after it became available. In the Camaro it was announced as available on March 17th, 1967, The Chevelle I am not sure of the date on but I understand from other researchers that they feel it was introduced in either April or early May of 67.

------I have a friend on Cape Cod that is the original owner of his all-black 67 375hp Chevelle. He drag raced it extensively, sold it and many years later tripped over it at Carlisle and bought it back as basicly a basket case. Last I heard he is still putting it back together........Bill S

Is there a way to determine which engine came in a 1967 Chevelle that no longer has the original engine or paperwork? Is there any parts or any other options required to be a 375 HP car? Is there anyone I can contact that is an expert on this subject? I really need to find this information fast. Any help is greatly appreciated.

I would contact either Jeff Helms or Dale Mcintosh...They have studied 67 Chevelle FACTS extensively and are guys that I consider 67 Chevelle authorities

[Hawkeye]

Thank you. Can you PM me their contact information or give me their usernames. I really appreciate the response.

Does your car have the original rear end? If so,what is the code? In my own experience the majority of these cars came with 3:73-4:56 posi,4:10 being the most popular. If your car has a 3:08,3:31 or a open,I think you have less than a 10% chance.

The car has KK code 4:10 posi. Will the fuel line tell me anything? What date code and plant would narrow the possibility down. Is it since the L78 option was dropped from the line-up would 67 L78s be an early build? Like an 11E build date and Baltimore plant?
Thanks for all the responses.

Interesting, I know someone who may have his protecto plate...Feel free to PM me if he has interest in checking for a match!! Also want to add that I know of a few orphan 67 L78 blocks with original untouched pads...So we may have his original block as well!?

IMO, part of the reason for the higher 66 L78 production number is because the 66 Chevelle was the only car to sport the L78 as an option when new. It was a new and attractive body style sporting the powerful 65 vette L78. (although there were some engine differences)

As a side note, there are a couple of documented 66 SS L78 Chevelles with 425hp ratings. No known engine differences when compared to the 375hp rated engines

In 67, the Chevelle had to compete with the new Camaro and its various configurations/conversions. Not to mention that an L78 Chevelle in 67 was essentially old hat...just my opinion
