Sorry if this has been discussed, I i recently had the collapsed lifter problem. Well the cam lobe finally gave out and no longer hold the rocker tight against the valve spring. So tomorrow I'm starting the tear down to put the cam in. I ordered a comp cam from jegs, part number 54-450-11. I was looking for any pointers, tips, tricks, or if anyone has done a cam swap themselves for the first time how long did it take? If there's a thread on this already, I'd like a link, I'm on a cell phone so searchings time taking and slightly difficult. if not, I'm willing to be the guinea pig for documenting the project. thanks in advance for all reply's and suggestions!
