Im workin on a 440 that was just built for my buddies car and i put it in a fired it up..did the cam break in procedure for the comp cams hydr. 305h magnum...."it has single springs so i didnt take them out"..and everything was fine so i changed the oil and then started in on the carb and fine tuned the timing when i heard a slight tapping.I immediatley cut it off and pulled the valve covers.It has adjustible rockers and some were loose so i started to adjust them and then realized they were too loose...uhoh..soo i pulled the intake..to find that the lifters are ground down so far that the pressure spring inside is riding the cam on a few lobes...jessus...well the lifters spin freely and there is no bind and all the oil gallyes were wet and lubed...no blockages..and the springs dont have too much seat pressure for the combo...but what i have to ask i see all these parts places sayin there is a difference between solid and hyr. pushrods..?The pushrods that are in this motor have no oil passage on the bottom and i think thats the problem.. I need to know any info especially the pushrod question...do i have the wrong set?I didnt build the motor and the guy that did was a [email protected] im a chevy man so i need yall guys help....If you could email me any answer i would greatly app it..i have to get this car running so it can get to the body shop..thanks in advance. -josh
