Default Engine number Help!

I have an ex Nevada, early '65 Vette coupe (S101479) with 4 speed manual transmission. I bought it 6 months ago and it has been in Australia for 3 years. In most respects it looks really original.

I am having a lot of fun restoring it bit by bit.

It has a carter AFB 3271SB carb which according to the black book is correct for the most common 300 hp engine.

My problem is the engine number on the rear left hand side of the block does not match any GM number I can find in the black book or on the web - it is 3914860.

Also the stamping on the right front of the block T 0328 EC I presume is a Tonawanda block built 28 March but year unknown to me, nor do i know what EC refers to?

I realise it is not matching number engine but i would like to know iwhat it came out of and what age it is for parts/capacity etc

Can anyone help?

John

Could it be 3914660 ??
That would make it a: 1968 327ci 210hp-275hp with 2 bolt mains; probably from a Chevelle....the "EC" code may be an "EO".

EC would also be a valid code, still from Chevelle, 300hp in '65 or 275 in '66.

Thanks for taking the time.

Sounds like Chevelle it is, and I am going to double check the numbers, it could be 3914660.

Two bolt mains doesnt sound that strong or vibrationless to me, but it pulls like hell and I am about to put headers on it and TI so I hope it doesnt rattle itself to death!

Is there any year code stamped on the block anywhere? - that would pin things down real good.

Two bolt mains can handle a lot if built correctly. headers and TI wont hurt a thing.

no date stamp but rather a cast date just like the casting number. if you look on the back of the block on the passenger side towards the top you will see a set of numbers in the format of = A 65. that would be January 1965.

His is a Tonawanda block, so it will have 4 or 5 digits (the year portion will have two digits, vs. one for a Flint block).

Unless you are heading North of 6,000RPM (regularly), 450HP or 500 ft-lbs of torque....you'll be fine.

I checked the block casting numbr and it is 3914660 which puts it as a 1968 210 to 275 hp as you state.

From here it gets interesting - the T 0328 EC engine block stamp is very clear and there are only 2, 327 V8 codes I can find - 1965 300hp special high performance Chevelle and 1966 275 HP Chevelle/1200. i cant see how they can cast the block in 1968 and put it in an earlier car?

I checked the VIN which is clearly stamped next to the Engine code on the block - it is 18Z143813. I have been trying to match that to a Chevelle VIN to try and pin down the year but no luck?

If the block was ever decked there are those that will (and do) stamp whatever you want on the stamp pad - commonly known as a restamp...

Are you sure it's not 3814660 which is a 1968-69 327?

The VIN derivative stamping pegs it as from a '68 Chevelle or El Camino built at Fremont, California, and the "EC" suffix says it's a 327/275hp Powerglide from a '68 Chevelle or El Camino.

The end of yr sentence was not there but I will recheck number, that number looks like a looks like a 68/69 327 "FA" (whatever that is ) or a 68/69 302 Camaro which i dont think it is.

Interestingly, John Z above , pegs it as a 68 Cevelle or El Camino.

Thanks for the reply John, that appears to match the engine block casting number 3914660. There is a number on the left hand bell housing T16 as well.

Is there a book or website that i can get that gives this VIN info, all i can get on the web so far just conflicts.

I don't know of any one place that decodes all the possible variables that make up the VIN derivative; it requires multiple references.
