I have recently acquired a 78 280z with a l28et swap from an '82 280zx. Right now it takes forever to start, and when it does it will not idle at the normal 7-800, but has to be at 1000 at least, it also runs rough and climbs rpm's hesitantly at times. I'm thinking timing, but was also going to check the cylinder compression- but I can't find what the compression numbers should be... anybody know? Also any other ideas about whats wrong would be appreciated.
