Default Block to ID please

I’m having a difficult time finding out where this block came from.

When I looked up the casting number 3970010 the Corvette Blackbook says 350 1969 through 1980,
an internet search says it’s a ‘69 Z/28 302.

The stamped number 06191DJ has me stumped on the “DJ” and what is this code for?

As always your help is greatly appreciated.

I can’t get back to the car until Wednesday night. Is the cast Date Code needed to figure out if it’s just an average 350 and if the date code is within the time frame of the 69 model yr then it’s a Z/28?

Where is the cast date code located on sbc?

the code sez it is a 58 or 66 283. don't think they used that block for 283's... ignore the stamp. it is blue. 77-up color. a few Z28 302's were made with the 010 block. a few million 350's were made with that block. some kind of special. most plain Jane car or pick up truck motors. you didn't win the lottery.

V=Flint
06=June
19=19th day
but the last 3 is the engine code suffix IDJ? All 3 are alpha, not the number 1 followed by DJ - correct?
So now what is the year, engine and model?

the Blue is the same paint on the body, it’s not the corporate Blue we all know.

I haven’t even started to think about the floating “SP” to the left and under the engine code yet.
This puzzles me, I never knew Chevy to put a screwy code on a Factory engine (ie: V=“Flint”) and it’s either V06191, but date codes must be 4 digits! V0619 then “I” with “DJ” but I can’t find any 3 letter suffix codes.

Normally I would just toss it up as a a royal pita but yesterday at church we met the fiancé of a injured vet and she’s trying to recover parts to a car that was slowly picked to pieces by some neighborhood low-lifes during her boyfriend’s deployment.

Thanks for your help,
Rich

Without a vin it was NEVER installed in a production car or truck. However it could be a marine block or a machine shop stamp

Good point, an 010 block with no VIN is very likely a common over the counter part.

The SP could be a rebuilders stamp or even someone’s attempt at marking his property.

The "010" block is common to any SBC built between 1969 and the late 70's. "010" Used on a '69 Z/28?....yes it was, on just some of them BUT keep in mind the "010" bock is the most common block casting used for SBC 350's for around 10 years too, so the internet search is backwards. It could have come out of a station wagon or a pickup truck or anything else during the decade. It is not specific. Can be 2-bolt main or 4-bolt main.

I think GM cast just just about a million of the 010 block it was used in EVERYTHING from van body trucks, cars, trucks, LT-1 and race cars. The suffix code on the block is not one for ANY car or truck application for that block. and ANY car or truck built after 1968 required a vin stamp on the engine block.

The stamp pad shape changed in mid 1977 to a squarish shape. This is a 78 as an example so not a late 77 or later block.
