Some of you have probably noticed that these "HEMI Tech" threads have been popping up. I've been trying to merge the info on here for our reference making searching easier. I'm going to try and start threads related to each topic related to Hemis... problems, parts, tech, etc. So sorry if this is sounding repetative to what's already been talked about. Could use your help to merge all this info on here. Links (HAMB or outside on the WWW), your own tech, etc. would all be very appreciated. On to Camshafts... 1) Regrind to spec... - cost effective or not? - What's the advantages or disadvantages? - What's the grind limitations? 2) New cams... - who's still making them and who makes a quality product? - vintage aftermarket cams to look for? 3) Interchangeability... (all makes) - What can be changed between what engines? - When should a cam change be made? (I.E. 331 cam for a later "snub nose" cam) 4) Solid, Hydraulic or Roller lifters... - What's better for what application and why? - Who's a reputable supplier for lifters? Throw in any info or tech you have. All will be helpful and will make the HAMB an even more powerful information Library!
