I am buying a stock 351 Cleveland, 2v heads where someone has installed a four barrel Holley carb and an aluminum intake. It has factory headers. I would like to increase the horse power and find out how to modify it for the oiling problem that these engines are known for, and do all the work before I install this engine. What do you suggest? Cam? If so, specificly what cam and what are the specs that would work best for everyday street and weekend strip driving? Is the stock cam good for this or is it a good idea to replace it? Open to any and all ideas. Thank you.
