When I disassembled my engine I went to great lengths to keep the lifters in order so they went back on the same lobes on reassembly. Things looked prety good and I was going to re use the cam and lifters. Made a really stupid move today and the lifters got scrambled. Took careful look at everything again after scrambling the liftersand while there is no real obvious serious problems, there are a few lifters with slight imperfections that concern me now that the lifters will not be going back on the same lobes. I could put it together and it may work fine, but if it doesn't, replacing the cam after the fact will be a whole lot of work and another gasket set. I have prety much talked myself into biting the bullet and ordering a new cam and lifters from Mummert. Opinions?? By the way if anyone heard loud noises from the direction of Southern Illinois, it was me cursing.
