I also am building a 261 (1957) very similar to Chronamyd except solid lifters. Where can I purchase a suitable camshaft? I would like a stock type 261 solid lifter camshaft. Can anyone suggest where I can purchase a GM 3836484, Elgin E-293s, Sealed Power CS-293, Engine Pro MC-293 or Melling equivalent. I have been told the Melling to the 3836484 is CCS-29. Has anyone used their CCS-1 camshaft in a 261? Thanks Bob
