Lunati VooDoo Question

Lifters are seldom the problem. Noise and failures are ususally more a function of setup and less often the block itself. Have you measured the lifter bores on your block? If you had a bad one, and now have the same issue or worse (cam gone bad), and neither was with a modern cam grind - chances are you have either a setup or block issue. What oil are you running? What is your oil pressure hot at idle and at 3K? What is your lifter preload?
