Hello, can anyone tell me if I can define the standard horsepower of my engine by the casting number? I have a 71 c10 with a , I believe, 1986 350 engine.
The castingnumber is 14088548 which I found on the rear of the engine on the passengerside.
On the front side I found the engine number I think but it is very hard to read. I want to define the Suffix code which looks to be UPN. But this code I cannot find back as being a suffix code anywere on the net.
Thanks fro any usable information !!
