If you have flat top carbs my best advise is to replace them as soon as you can . I just bought a set air cleaner carbs and linkage $190.00 and have another set I got for a friend just the carbs $75.00 the next thing to look at is the ignition get one from a '79 zx and get it all the dist and its mount and the coil. it has a module on the side of the dist. marked 12 80 that is the one to get. The thing that was brought up about cal and emissions is another thing if it effects you. My 73 runs great with round tops and the ignition . the carbs are from a 70 .. good luck

Fly, I put my '73 on the scale and with me in the car , 230lbs the car went in at 2600 lbs with a full tank and all the stock chrome. But what I found interesting that when I weighed just the front end again with myself in the car 1300 and the same with the rear. I had no idea that the ballance was that good. Who would have" thunk it."

Dutch, Maxama trannys will work that is from the cars with the inline six engine and they are 4 speeds. so if you go with a 390 diff you have the best of both worlds.

A good place to look for a Z is in E-Bay the best area to find a rust free car is in AZ, CAl , because of the dry weather, however I live in Oregon and have found several cars with vary little rust. The key here is if the car is garaged or not, no salt is used on the roads so rusted out cars are few and when you find one its usually an import from the mid. west , or a beach car. I found my present '73 240 here in Portland for $500.00 . I need only a little body work $600.00 worth and then paint ,which being relistic ,will run about $1500.00 If I do the prep ,and they only need to do the final prep and mask. I am keeping the stock red (orange), that way the engine bay and all the jams are ok with out repaint. You may need to travel to find a really good one especially if you are looking for a 240 . Best of luck to you , and dont be in a hurry . "You have to kiss a lot of toads before you find a prince" so the story goes. Ha Ha

The recomended weight is 20w . I have been using Mistery oil for a long time but have noticed a lag off the line if I dident have my foot in it. Just a slight stumble and couldent figure it out, but I recently tried some 20w and all is right with the world. The thicker oil allows the piston to rise slower thus giving a richer mixture into the engine before the slide rises. The difference is only a split secound but just enough to clear up the problem. If you are running with an open throttle , like when raceing , then it dosn't make much difference because you are always in the powerband and with elevated rpm. but for street use do your self a favor and try 20w. The only place that I have found it available is at the local motorcycle shop and it is sold as fork oil. As far as the level needed if you over fill the dampiner it just runs out and is burned with the fuel no problem.
