Wow.....interesting ad. I think he needs to do a little more research on these cars. A little overpriced as well. Neat car none the less.

L78 Impala with a 4 speed buckets and console over priced? Looks like a tough one to find.

- The L72 was not rated at 435 hp

- The L72 was not the same motor as the 427/435 in the Vette

- The L72 didn't require COPO channels to be ordered

- I believe 546 L72 big cars were built per Chevrolet records

- Chevrolet usually built more sticks than automatics with their top motors

- I'd be willing to bet most of the L72s were ordered for SS 427 cars over any other big car

Diego,

Other than induction (3 X 2 vs. 4 Barrel Holley)all the internal parts are the same for a L-71 &amp; a L-72 Big Block I thought.

Yeah, but it's still an incorrect claim. He'd have a whole lot more credibility if he said it was the same engine as the L72 Vette from 1966 and the COPO Camaro frmo 1969. :twocents:

I actually owned a L72 66 vette back in the day. From what I have learned present day the engines were the same except for casting # head casting # and a few other not important #'s. I always thought the 427-435 was the L88, and as such would not even be close to the L-72......?

The L-72 engine in a any Chevrolet 1966 to 1969 was the same: internal compression, head configuration (rectangle port / combustion chamber rating) as any year L-71 Corvette engine. The only thing that changed from 1966 to 1969 was casting numbers of the block &amp; cylinder heads, drilled holes ect. for sending units &amp; accessories.


In 1966 &amp; most early 1967 engines, the camshaft had the &quot;Groove&quot; in the back for oiling reasons and they will not interchange with the later non-grooved camshaft. The specs. of the camshaft I believe are identical. That's what I remember.

It's an L72 which is better yet but still over priced in my opinion. I have owned MANY of these cars so I am saying that from experience not just opinion. They just do not bring the money even when totally restored which is a real shame. As I have said in other discussions, I know of a certain L72, automatic SS427 convertible that is rough but 99% there and he was asking $15k 10 years ago and he STILL owns it so I must not be the only one that thinks that.
