So I have a motor from an older year vehicle but I do not know what year this motor came out of. I’m think it’s from 1973 but not sure so I just need some help identifying I’ll give you guys as much information as I can

13Z440022

v0207ckd

GM casting # 3970010

 

Comes back as:

3970010Manufacturer: Chevrolet

Category: Engine Blocks

Type: Small Block V8

Date: 1969-1980

Notes: 350, 2 bolt or 4 bolt, may be mistaken as 8970010

The post-1972 motors are worthless as they came with low-compression motors, due to SMOG regulations.

 

CKG:
1972 , 307, 130hp, 2 bolt mains, 2 barrell carb, manual trans

 

I’m trying to get the suffix code and get help with the exact year and maybe model with the other numbers
