I'm from Cincinnati and have a '72 240z. I originally dragged the car home from Northern OH with the intention of dropping a 5.0/T5 in it. However, buying a house and getting real into hot rods and bikes sidetracked me. Since I'm also building a couple choppers, a '58 Olds with a J-2, and an early caddy-powered '31 Model A, I've decided to leave my Z close to stock and get it on the road with the 6cyl/4 speed.

So far, I've completely rebuilt the front brakes/wheel bearings, replaced ALL the hard lines, and replaced ONE rear wheel cylinder. The PO had bolted the wheel cylinders in place in a misguided attempt to stop them from sliding in the adjustment slots. I still have problems keeping a firm pedal for more than a day or so. I'm picking up a new master from Advance Auto today and am hoping that'll fix the brakes. If not, I'll replace the other wheel cylinder.

The other issue was with overheating when I was driving it. It didn't actually overheat, as I shut it down before it got bad, but the guage was climbing. Once I get the brakes working, I'll check the timing, clean the carbs better, and do some of the other typical things to fix overheating. I also may hook up one of my mechanical guages to make sure my sender's not just bad. If worse comes to worse, I guess I'll HAVE TO swap in a good running L28 or L28T.

Over heating can be an issue with these cars but most are easily fixed.

Flush the cooling system

Put in a 180* thermostat

Check the Waterpump for flow.

I like to use REDLINE Water Wetter during the summer. I can reduce the heat by up to 15 degrees.

I also like to park uphill to allow the air in the system to make it's way to the top of the radiator and fill accordingly. This eliminates Hot spots and gives you a solid liquid system.

Welcome to the club and good luck with all those cars.
