I need help to ID a motor
Hi,
I've tried to identify this GM V8 with little success.
I looked up sites by posts from folks and still cannot ID.
The numbers I can see are as follows:
At the rear of block: 3970010
On the passenger side front pad, there are (2) sets of number/letters.
The first set are smaller than the second set.
1st set: 14J248511 2nd set: V0603 CMR
Can anyone decipher what this motor is and what it came out of?
Thank you.
Rudy

1978 350 L82 mt.220hp 4bbl Vette/Z28
1980 305 thm 155hp full size
You need to look for the casting date to tell you what year you have

Re:
BSiegPaint,
So its a 74 145 hp 350?
I guess the casting date would mean nothing at this point.
After doing a bit more research, I did see the above info.
Thanks for confirming that. It also said it was from an "A" body.
Do you know or anyone knows what models in 74' were an "A" body?
Thanks.

The V0603 is the assembly date (June 3rd) and not the casting date. The casting date is located on the other side of the block from the casting number, back by the bellwhousing.

Re:
To all that have responded:
I appreciate all your help here.
I'm inexperienced at a lot of this and my questions may sound stupid,
but I am quickly learning with all of your help so thanks for that.
If the motor originally came with an automatic and is hooked up
to a 4-speed manual, will the drive train be ok?
I have transmission questions too.
The numbers and locations I found are as follows:
Drivers' side - Rear: 3952648
There are what appears to be (2) clocks embossed on the casing.
The first reads 3:45 and the second, 10:20.
There's a metal tag on it as well. The numbers are 7M110896.
Passenger side - Rear: 392561
Then, US Patent # 308833 with the last number as an 8 or 6.
Many thanks.
