Unknown engine and transmission
I have a '68 coupe that was originally fitted with a straight six engine and 3 speed manual transmission
The previous owner has however fitted a 302 V8 and auto transmission
Problem is I do not know the origin of the engine and transmission!
The casting code on the:
1) intake manifold reads D9DE -9425-DB (spark plugs are 10mm Atlas C36124)
2) transmission reads C6AP 7DO27 - C
As I will need to order some parts and set up the engine timing (any tips here??) any information you guys have will be of great help.
