well it happend! a while ago i noticed a small rocker tapping in the valve train so i thought it was the lifters since the motor sat for long periods of time. i replaced them and what do you know they started to tap again. so i got pissed and pulled the motor out to see if what the f--k is going on. i want to check the oil galleys/bearings to see if i got oil and if they were pluged. i'm having the block rechecked to make sure its clean. it turns out 3 lobs on the cam are gone. i haven't driven it more than 3 miles since the rebuild! i did not know about the federal mandated zinc removal in motor oil. upon checking i found that a roller cam is better for todays oil. is that true? i have 9.5 compression tripple springs and set the valves up for unleaded. besides the cam and lifters are there any other things/changes i need for a proper set up? im going street only no racing because of the #matching engine. any answers will be greatly appreciated.
