85 SBC No start

Hello, can anyone give me some advice? Here is my dilema. I have a '95 Nissan 2WD hardbody truck. My dad and I completely rebuilt an '88 305 4-bolt main and put in there! This is the first summer I have driven it and now with the 90 degree heat and high humidity, it is acting up. After I drive it for awhile and shut it off, it won't start for about 2 hours after I shut it down. It won't crank AT ALL. The starter doesn't engage (don't know about the solenoid), there is gas getting to the carb, the battery and alternator are good, the plugs are good, and everything else seems to be okay. Could this be the typical Chevy problem I read about where the starter gets too hot? I don't think it's vapor lock or electrical(per se). Any advice ya'll could give me would be GREATLY appreciated!! Thanks!

Chevy did have a problem in years past with some starter acting up in heat but it is not much of a problem these days. Heat make be you enemy and cause here though. A lot of people shoehorn big engine in to small compartments without thinking about cooling issues and off road it can get very hot under that hood now. I would suggest that you install a clutchless flex fan that will aggresively always move air though engine compartment to keep under hood temps down in your tight installation. A little bit of fan noise may be the price of your conversion in hot weather as you need some constant postive airflow in hi volumes that a clutch fan or electric one is simply not going to be able to deliver. You can alway switch back to less agressive cooling during the cooler months.
