I am wondering how you would tell if a car like a 1970 Camaro or Impala has the numbers matching engine?
I have purchased a 70 454 Impala and would like to know if the engine is numbers matching???

Is the VIN stamped on the block anywhere?

Check down where the oil filter is. Along the edge where it mates the trans.. I think..

Dude, just out of curiosity, what's with the Brake master on the passenger side or am I missing something? Sweet project though!

Cuse he's from down under!

Just out of curiosity, do you throttle with your left foot, and clutch with right?

Unreal: King has to do that or he will fall of the face of the earth - lol

King I doubt that the vin# was stamped on the engine in 70. I think your best bet is to look at the Engine Assembly Date stamped on the Psgr side or that would be your Drivers side - lol which might look something like T1030CWA in this case a the Engine was assembled at Tonawanda Planet Oct 30th and the CWA indicates used in 72 & 73 Chevelles. If there is a partial VIN# stamped in the same location it would indicate the engine was assembled after 1972 and certainly would not be the original engine for a 70 car.

If the Casting Date and Engine Assembly Date a say is 1 to 9 months prior to the Build Date of the Impala, then the Engine is most likely original or can be considered original, providing the Vin# of the Impala signifies the car is a V8. Note that the Casting Date can be as much as 2 or 3 years prior to the engine assembly date but the Engine Assembly date should be within 1 year prior to when the car was built.

No, the rest is the same, except of course for shifting with the left hand. ;)

Not really. The casting date is typically between 1-6 WEEKS prior to the stamped engine assembly date, and the stamped engine assembly date is typically 2-6 WEEKS prior to the car's final assembly date. Occasionally casting dates up to six months prior to the engine assembly date are found, but that's not the norm.

This may help to nail it down..Cornbread

JohnZ: I'm Canadian, perhaps, we have longer periods between casting and assembly dates due to shipping time. I've a hard time convincing Americans that we had Pontiac Beaumont's with 396's and 327 Firebirds. I do know, frequently, casting were pulled off the line for whatever reason and stored for repair. If his Impala was assembled in Australia, the period between Date Times may even be longer, if not right out of this world - just something to consider - lol.

King I doubt that the vin# was stamped on the engine in 70 ...

Yes it would - the Partial should be on the same pad as the Suffix for a 70.

And I agree with JohnZ on the dates for castings.
They didn't stock pile block castings for seasoning, or repair (?), at any of the US and the McKinnon (Canadian) engine plants. They were moved to machining and assembly almost as soon as cooled and deburred.
The 'bad' castings were crushed and remelted into 'good' ones ...
There were minor exceptions due to lack of FIFO, and for holidays & etc., that lead to minor delays in casting progression to assembly, but they didn't lead to months and months of delays.

His Impala was most likely assembled somewhere on the west coast for export.
The RHD conversions were commonly done offshore by contract operations.
I got to visit the Corvette conversion contractor outside of Sidney many years ago.

Why would it be hard to convince someone that the GM Canada vehicles were basicly Chevy's and had Chevy drivetrains :confused:
I'm a believer :D

Vantage 68:

Here's some convincing.

Opps! Sorry the Canadian GTO and Firebird (big debate on Firebird) did not come with Chevy drive trains but our Pontiacs and Beaumont’s did. One of our most famous was the Beaumont SD 396. We had 68 Pontiac's with 427's and 70's with 454's plus the TH400 tranny what was not available to Americans using Chevy engines. These cars came with 12 Bolt Posi rear ends as well. I am positive that around 68 at the time when the Firebird Sprint with the Over Cam Inline Six were available there where some Canadian Firebirds with 327's.

Jerry Titus and Terry Goodsall of T/G Racing found a loophole in the rule book and used a '69 302 Z-28 engine and campaigned the T/A as a "Canadian" Firebird. The Canadian Firebirds did have the option of being equipped with the 302 engine.
