Would anyone know what this engine might have came out off?
I bought if from a salvage and the owner didn´t have a clue.
Casting# 3970014, it is a 2 bolt main.
Stamped code: T 1025 CMJ
Date code: J11 74
Head casting# 3998991

1;st pic, front engine mount bracket, the block does not have the side of block engine mounts.

2;nd pic, vaccum to distributor setup?

3;rd pic, flywheel is about 16" dia and the clutch is about 13" dia and it is a three finger type and the rear of the engine have an "adapter plate" to make it take a bigger bellhousing.

Would appreciate if anyone could help. I´m curious, would be nice to know.

Thank you guys.
It was the different motor mount bracket, clutch setup and some other things that made me confused, it make sence if engine come from a C60 truck or similar.
