  1. Thank you Diseazd, appreciate the feedback
  2. Thanks jonbill, The pistons are stock 73 style with the eyebrow cutouts.
  3. I'm using new 73 style pistons and want to upgrade cam to Comp Cams 280S-110 grind. The head has been surfaced at -.012. My main concern is valve clearance, I do plan to use cam tower shims but I'm unsure how many it might take to make this combination work. Thanks for your help. Specs for stock v. Comp Cams: Comp Cams Advertised Intake Duration: 280 Advertised Exhaust Duration: 280 Intake Valve Lift: 0.460 Exhaust Valve Lift: 0.460 Stock Cam L24 Intake Duration: 248 Exhaust Duration: 248 Intake Valve Lift: 0.413 Exhaust Valve Lif
  4. No idea how it may have broken. I've only owned it for a few months and am doing lots of restoration and upgrades. Thanks for the heads up Zed Head, I'll try to follow up with that
  5. First post. So, I just pulled my head to begin major cylinder head and engine overhaul on my 165k 1973 240z, and found that the cam locating plate was broken in half. Car was running fine but very low compression across the board that motivated the rebuild. I'm unable to find a replacement. Checked with Courtesy Nissan and does not seem to be available or local dealers. Does anyone know of a source for this piece? Thanks for any advice or suggestions.
