The parts list looks good- - - -depending on the skill of the rebuilder, it's probably OK. I'd be a little concerned with running hydraulic lifters, as the vast majority of the new ones available today have a really bad failure rate. I just bought the last hydraulic lifter stovebolt cam Melling had in stock, but I plan to get it reground to the solid lifter profile for the 261/Corvette cam, the Melling CCS-1. According to a conversation I had a couple of days ago with the tech support gut at Melling, they have 350 of the CCS-1 cams on backorder, waiting for a foundry to cast some cores to grind. He has no idea when that's going to happen. I have two brand new cams on hand, a Melling CCS-1 and an Elgin E-293S. I'm using them as patterns so a cam regrinder can make a master cam for reconditioning good condition used cams.
