ok I am going to blow through a lot of questions here I have a 1971 240Z i upgraded the alternator and now my dash and running lights stay on anytime the key is on what could cause this? Second last monday i swaped a 79 280 f54block n42 head with the biggest cam you can get without going to larger valve springs i bought the motor this way i put my brand new ztherapy 4 screw su carbs on it with the msa 6to1 header and the orignal bosch distributer and e12-80 module but it wont run right it backfires through the carbs when you rev it I did get it to run the other day long enough to set the valves at .012 exhaust .010 intake but Im not sure the coil is right it has a pretronix 3.0 ohm coil from the kit I put on the 240 motor when i got it i also tried a crane cam lx91 and it got worse so I switched back to the pretronix my plug gap is .042 i just need a starting place iv done everything i know how to do to no avail. what am I not seeing?

Hey Guys, I'm a relatively new Z owner.. I bought a 1971 240Z at the end of summer, and I've been trying to get it into top running form. One of the previous owners put alot of work into it, but one thing that has been giving me a headache is trying to figure out what to do with the ignition system.. I've done alot of searches, and research, but the more I learn the more I don't know what to do. Basically I would like to upgrade from the old points system to electronic ignition, and just get the best possible setup. From what I've read It seems everyone has a different opinion on which way to go.. It currently has an Accel super coil, but after reading the specs online I'm a bit worried about the part where it says "Effective up to 6500rpm". My 240 has a .280 cam and has been balanced to handle high Rpms, and although I don't like to do it, it will go past 7500rpm.. But now that I'm thinking about it I'm not sure its really pulling as hard as it should past 6500. Maybe I'm just imagining that though. (I would go test it right now, but since I can't get it through emissions testing I can't put regular insurance on it, which means expensive permits.. That and I avoid the wet weather like the plague.) I would like the ignition to handle up to 8000rpm to take advantage of the cam, not that I plan on taking it that high very often.. Then theres theres upgrading to electronic ignition.. I'd like something easy to upgrade where I won't have to replace the Tach.. Pertronix sells a kit which sounds like an easy upgrade, but I'm not sure if it will work with my coil, which I don't know if I should keep... And it all needs to look original, or be from the 70's-80's period for my car to qualify for a local Vintage car race I'd like to take part in.. ahhh, that headache is coming on again Part of this upgrade is to try and get the car running as efficiently as possible to help with the emissions testing.. If I can squeze it through without having to get it specially tuned, and retuned, while spending the money on what I should be upgrading anyways I'll be very happy. I'm really at a loss to which way I should go here.. Any advice that you guys could give would really help.
