I believe what the judging guide is stating is that all Corvettes would have the gussets.Since that is all that the NCRS manual covers.And as always if you have something that is out of the norm it is up to you to provide GM documentation that proves what you have is correct.Do not shoot the messenger.That is how the NCRS does it

My documented April built 65 L78 had the original motor in it. Casting 962,
with gussets. I have never seen a real 65 L78 Corvette that did not have a 962 block with gussets. Check on the NCRS website archives. That engine was unique to that year only.

The statement refers to the 3855961 case which was not installed in the 65 Corvette. Hence, the statement was made as a generalization not specific to Corvettes, and as such, is in error.

Also, since more than one 65 dated 962 block has surfaced, and the 65 dated 962 block supposedly was only put in the 2157 65 BB Corvettes and 201 Z16 Chevelles, would GM have made a different block for the 201 Chevelles? If not, where did these blocks without gussets come from and used in if not Corvettes? Were there any other original applications for the 65 dated 962 block?

the high horse Impala 396 used the 962 block. there is a local 66 Impala 396 with a 961 block he claims is original with the gussets. I have no clue on the build date.

The 961 block is a two bolt main, the 962 is a four bolt main. No 961 blocks would have been installed in a 65 L78 Corvette with 425 HP.

Am almost sure that the gussets were present from the start, and were still there at the end of Corvette L78 production. But they disappeared somewhere in the 1966 model year Chev pass car usage.

As seen on the first picture it says High Perf. Does it say the same on the High Perf small block engines?

Actually, I asked what other applications used the 962 block in 65 not 66 and later. I have found no other listings other than the Corvette and Z16 Chevelle that used the 962 in 65.

Do you have any references that show the 962 used in Impalas in 65? If so, how many were produced?

I do not know how many passenger cars were made with the 962 block but I do know that the engine suffix code is IE for the passenger car.I have seen mare than a few of these blocks and have owned a couple myself.They also use a different Holley carb than the Corvette list#3130.I also have an original dated one of those.It looks exactly the same as the #3124 from the corvette right down to the smaller fuel bowls

4-bolt main.
Seller says it is from an Impalla.
See F/s 1965 396 425 hp 4 bolt block 3855962

It has gussets but the clutch boss location is not 65 Corvette.

Hmmm This is an IE block and it has the gussetts, so apparently the passenger car version had gussetts also. So the question still is, what applications got the blocks without the gussets? Might they be a random annomoly? Could they be from a limited run? A run on the 961 line but made into 4 bolt and the 962 cast number? Any thoughts?

That rearward hole is in all Mark IV blocks - it was used for the clutch ball stud on Camaro (photo below) and Nova.

The question, JohnZ, is that a Corvette block?
I guess if it has the forward boss hole, then it could very well be a Corvette block.

Sounds like same block in Corvette and passenger cars.

a 962 block is a 962 block weather it came out of a Corvette or a Chevelle. the only thing that is different is the stamp on the pad and the internal parts.
