   Ignition Timing

   I have a stock 72 non-California 240Z. The manual calls for the timing to be set at 5 degrees BTDC. Since this car is now exempt from CA emissions tests, all the emission crapola has been stripped off the engine. Someone told me that, when this is done to this engine, that I need to change the timing setting to 17 degrees BTDC. Can anyone confirm (or poo-poo) this? thx, Jon W. thebigboy@earthlink.net

I was wondering if this is a good head to ues or not. Not the best head for performance. Low compression and poor exhaust port design. N42 is what I'm using. Higher compression and the preferred square exhaust ports. Others prefer the P90 turbo head, which also has square exhaust ports. I would like to >be able to drive this car on the street and be able to use pump gas. With the N42 head and a 2mm HKS head gasket, I'm at 10.14:1. somewhat steep, but I ran mine like this with the stock cam (hot…

   headers

   I have a 71 that I have dropped a 280 motor into. It runs so quite. It has the orginal double muffler set-up. I was going to take it down and have the exhaust changed to 2.5" and a single generic muffler. I got to looking at the orginal manifold that would still be there, looks small to me. Does a header give much more power? Where is the cheapest place to order z parts? I tried to buy a gas cap yesterday for the 71, it was 37+tax seems a little steep to me. thank you for the infor.
