Good sign or maybe every one is just excited about getting going this spring. I need some suggestions, Due to my extreme rambler mentality, I would like to install a used performance cam in my 304. The lifters are dished that I pulled out with the cam. How bad an idea is it to get a new set of lifters and install them along with new cam bearings and the used performance cam. The cam doesn't look bad with the naked eye, I suppose I could mount it in a lathe and check the lift specs, what do you suggest?? Remember my rambler mentality now LOL. ********************************************************************************************************* I'm going to add my 2 cents worth as while Frank and some others have hit on the oil problem, ie most of the moly and zinc has been taken out of the engine oil used today. Even Shell's Rotella , diesel oil no longer has most of it's moly or zinc as Of January 1,2007. The cam may be ok. It still needs to be checked, but the lifters may have been bad. There has been a lot of junk made in China ,flat tappet lifters running around and they are total crap! I've got one of my old Mopar Homies back in Illinois who was on his 4th engine rebuild on his 67 Big Block Dart Convertible due to lack of moly in the oil and especially bad hencho in China lifters. There is a good article on this in "Hot Rod Do-It-Yourself Series Engine" special called "When Good Cams Go Bad'" , page 72. Even diesel engine have catalytic converter now and the moly and zinc fouls them up, so our beloved government has mandated little moly or zinc be used in engine oil as of Jan.1,2007. And lastly hydraulic flat tappet lifters are BUGGY WIPS ! No modern engine in production uses flat tappets any more. All new engines currently made are Over Head cam or roller lifter. Roller lifters use to be rather exotic, now are common. Still expensive , but common. So if you rebuild an engine you add a $6 bottle of moly oil additive or look for a $600 AMC street roller cam setup. (Not to Nick Alfano , looks like some needs to step up and start providing the option of an AMC Roller lifter street cam setup.) thanks LRDaum _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
