Crower solid flat tappet, but was setup with a gear drive, with a thrust bearing behind the cam gear, and a thrust button in front. Unfortunately, it looks like they set the cam up to center the lobes under the lifters, which is also a no-no, and it had basically no lifter rotation. Allready had worn all the crown off 3 or 4 lifters, and lobes worn pretty significantly for the small amount of run time it saw. Going back with a solid roller this time
