well for the past month my trucks been apart. ive put on new heads, and a comp cam. after attempting to break in the cam ive had a ticking noise. i pulled the valve covers and re-adjusted and re-adjusted.....after the first change of oil i saw fine metal dust in the oil.....ran it some more, and there was a little more metal in the oil filter. i pulled the pass side valve cover to see that one of my intake rockers wasnt lifting as nearly as much as the others. SO i pulled off the rocker and pushrod and tried to pull out the lifter from an oil galley and it will only come up about 3/8 of an inch...makin me belive that the lifter is mushroomed and cant come up through the lifter bore...... i followed all the break in procedures and whatnot from comp now i have to take the engine back apart. Summit will refund my money spent on the camshaft and lifters. now my question is do i go with that same exact cam and possibly have to take the motor apart AGAIN.....or try a hydraulic roller retrofit cam...... this will cost a few hundred dollars more but will eliminate break in problems. i would also need shorter pushrods, new roller lifters, cam button and wear plate so the cam cant move, along with some gaskets..... this will also increase hp and tq. desktop dyno says 550 ft lbs of tq @ 2,500 rpms and 400 hp @ 4,500 rpms anyone experience these roller cam retro fit kits?
