looking for some info my uncle just got a engine and its stamped c9oe-6015- and it looks like a 1 or a L after that we thought it was a rare 302 or something but some research on the web says a 69 351 but nothing on the last numder or letter can anyone help me out and there anything special about the 69 351 if thats what it is thanks

 

I believe that was the best year of the 351W in terms of performance, do you have the whole engine or just the block? From what I remember the only special versions of the 351W were the police interceptors with 351 Cleveland heads. Or what was considered a 351 clevor

 

engine is complete one of the wierd things about it is it has a factory ford intake that has ford stamped on it but its built like a edelbrock performer i also was reading the 69-70 has larger valves

 

over my head!
