I had need to change out the cam in a new build 351W. I used sixteen 1/2” longer 5/16” rocker arm bolts and left the lifters and pushrods in place. I rolled the engine upside down and turned the cam around once. I pulled the cam out with the engine upside down and just as easily installed the new cam. I turned the engine back up right side up and changed back to the stock rocker arm bolts. I didn’t have to remove the intake manifold and saved time and money. This will work on any Ford engine with bolt down rocker arms including the 302, 351 and 460 c.i. engines, and maybe others.
