Engine pad re-stamp???

[JHS]

I know the engine is not original to the car so the assembly date is not at issue. I question the location of the Tonowanda stamping location: on the right side of pad vs the left side. I was interested in getting a correct suffix code & cast# block (CKO) but am now questioning that. My pic won't upload even though it is 888KB. Not sure how to make any smaller.

Is it at least a 4 bolt main block?...look for the external Oil cooler provision.
Email that picture to me & I will shrink & post.

Would the CKO code be correct for a 1970 Camaro, Nova or Chevelle? If so, it might be a legit engine and stamping but it would be too early for a 1970 Camaro L78. It might be a Nova or Chevelle engine. I think you need to host the picture on a website to upload it.

Yes..All three of those Models shared the CKO/L-78 engine suffix in 1970.
Here is the Pad Picture from JHS.

My 70 L-78 Camaro, built 01C Norwood is THE earliest one I know of. It has CKO engine assembled in Nov, cast in Oct.
I would certainly think that a Aug assembled CKO would have been installed in L-78 Chevelle or Nova. I would bet under CLOSE inspection you could find a partial VIN # stamped on lower left bellhousing flange.....starting with 10(1 = Chev Motor Div 0 = 1970) and then a LETTER for car plant nad 6 digit VIN #.....

Does your pad have the assembly info/VIN info on the pad or is the VIN stamped by the oil filter/bell housing flange? I thought only a few BB's were stamped with the VIN by the oil filter and that was in early 1969? My trim tag indicates a 03C build date.

[Mr70]

Have you determined if this is at least a 4 bolt main block?
On Van Nuys assembled 1970 Chevelles,it's not uncommon to find the last 6 digits of the VIN# stamped into the boss next to the Oil Filter.
I know of a few that were built in March 70 that have it.
What stymies me is where your Tona date is stamped.
Never seen it that far right for this vintage.

The VIN on my L78 and most of the other original 1970 L78’s is stamped at the rear of
the block by the oil filter. My car is a first week of June and it has a November dated
engine. Where at in Kentucky did you find this car? Mine was found in Morgantown
Kentucky after sitting in a barn for 24 years…
PS, Nice pictures Chuck, Looks like you getting better at this.

Below are a few misc pics to help with ID'ing 1970 Camaro's L-78 and otherwise. I show a CKO deck stamping from Tonawanda....where the number ONE looks like the LETTER I.
On the deck with CKO it also has a "L" Vin stamped which was common for Los Angeles........but Norwood 70 Camaros usually (I dont know so cant say always) had the VIN stamped on Bellhousing flange as did the pictured "W" Nova CKO.......
