I have a 84 chevy 350 in my 89 S10 blazer and was running good when I first bought it. Then I lost a lobe on my cam and I replaced the cam and lifters. I checked the push rods and they were ok. New gaskets and all...Two weeks later, lost the same lobe on a new cam. I have asked severl mechanics/ friends and everyone is stumped on this. Any one out there have any idea what might be going wrong???

 

Maybe something having to do with the cylinder or piston causng it?
