Noisy lifters after new cam on my 340????????

[Jay Hansen]

I had my motor rebuilt 1500 miles ago but it didnt have enough cam so I took it out and stepped up a bit too A lunati cam with 230 duration and .480 of lift. It cam with lifters .At first the timing was off or degred in wrong but It ran for a week then I took it apart and set it right. now the lifters are really noisy?/ I think ??? MY oil pressure is fine when its cold 70 psi then it warms up and drops too 5-0 psi. Is this my cam bearings or should I use mopar lifters???

Sounds like your oil pressure is causing all your problems. If you tear down your motor, don't be surprised to find wiped bearings all through it. I had a similiar problem and traced it down to a cracked #5 main cap. No clue how that happened... anyways, the cam settled, had to turn the crank (again), etc. If you fix the oil pressure, you probably won't need to worry about the lifter noise.
