Which engine has he in his Dodge ?

[ThomasBorchers]

Hello !

A friend has a 1958 Dodge Sierra Custom. He knows that he has not the original engine in it. The owner before him said it is a 1970 engine. My friend is not sure which engine he has. A 1970 ? A Dodge ? A Chrysler ? He has to set the timing and has to know which engine it is.

Here are some numbers he found at the engine :

Location : Close to the distributor : F 383 5 14 R

At the engine at the bottom : 4 14 70 2468130.9 N

Then some times ago he found also these numbers but he can't remember where they were : OC 235751 or OC 355/51

Can somebody help us ?

Greetings

Tom
