Roller cam/lifter problem

FWIW I got at least 25,000 miles out of a Lunati Voodoo hydraulic FT cam and lifters; when my 360 took a dump I pulled that cam out and aside from fairly normal-looking wear there was no damage to any of the lifters or cam lobes. Initially I ran typical off-the-shelf Valvoline full synthetic with Lucas Break-In zinc additive, then switched to the Valvoline VR-1 with zinc in it (intended for FT cams), then switched to Brad Penn. As long as the oil you're running has some zinc in it the cam and lifters will last a very long time.

With that said I'm building up a junkyard Magnum short block and intend to get a Racer Brown custom-grind long-snout hyd. roller cam mainly because the block is already set up for it and I got all the original roller lifters and "spider" retainer with the short block when I bought it from the junkyard (quite a bit of money to buy 16 roller lifters new). I'm not thinking it will give a huge power increase vs. a custom-grind hyd. flat tappet but the peace of mind of not having to worry about zinc along with the reduced internal friction at lower engine speeds will be nice. When I pulled the factory roller cam out of that Magnum block it looked great and that engine had at least 150k miles (didn't know the actual miles since the dash was gone from the donor truck I got it from).
