1965 396-425HP corvette Z16 engine

dlv is correct on this one. 65 offered 396/425HP for Corvette as well as Chevelle.

Donut,,,Did you mean to say Chevy??? Z16s were not the same engine as Corvettes. Seems like we just went over this. Corvette style 396/425 motor was available in full size Chevy briefly at the end of the 65 sales year but had a different code from the Corvette motor.......Bill S

Bill,

I do not think that George is saying that the Z16 is the same engine as the Corvette....he is just saying that Chevrolet offered the 396/425 in the Corvette and the Chevelle....not the Z16 Chevelle.

Bill, Dan is correct I was only acknowledging that dLV was correct about the 396/425hp offered in Corvette and Chevelle. (Period) Friend has a 65 Vette with this very original motor in it.

The heading of this post states 425hp & Z-16. That was what prompted my comment, merely meant to be a minor correction rather than the beginning of an argument.
According to Chevy's production figures there were only 201 396cid engines installed in production '65 model year Chevelles, and we all know they were rated at 375hp. Show me some proof that any Chevelle got a 425hp engine.
Two 396 engines entered production for '65 full sized passenger cars: The L-35 (325hp) with a total production of 55,454 and the L-78 (425hp) with a total production of 1,838 compared to Corvette production of 2,157.
Actually, there wasn't even an RPO# assigned to the 396 engine used in the Chevelle. Z-16 was an entire option package that included that engine, along with many other components, similar to the Z-06 or Z-11 ('63) packages.

Verne's correct...but on that last part, didn't GM label the Z16 engine the L37 although you couldn't order it without the whole Z16 package? .

Pete,
As for the "L-37", you may be right, I really don't know. I was going by an authentic Chevy list of options produced in '65, broken down by model. For the Chevelle, the list did not show any 396 engines optioned at all, only the Z-16 RPO. Maybe an orignal Z-16 window sticker might show a breakdown of all the equipment and list the L-37 Or maybe it was in some dealer ordering information which explained the option contents.
No offense meant to anyone. I was just trying to be factual.

-----Verne has gotten across what I was trying to say. There was no 396/425 motor factory installed in a 1965 Chevelle. Only 1965 Corvettes and a very few 1965 full size Chevys got the solid-lifter motor. The Z16 1965 Chevelle motors were 375 horsepower and had hydraulic cams although they appeared visually to be exactly the same as a 425HP. I hope my post didnt come across badly. Just stating the facts........Bill S

I was stating that this could be used as a Z16 motor as well as being used as the original 396-425HP set up that is originally was. The casting numbers are all the same and the chevelle used a different carburetor number and exhaust manifolds as well as a different distributor but all of the main components I have advertised could be used for one application or the other. Maybe it was my error to advertise it the way people advertise this on ebay. I see chewhoe in California selling these blocks decked and as a long block minus the intake as a corvette or Z16 applicaion because the front pad information is misssing. I wasn't trying to confuse anyone just stating the facts that the casting numbers are interchangeable.
