i just finally dropped my engine in finally after the rebuild, we replaced everything i go to turn the on and the engine turns over and then catches then stalls all in about 10 seconds. what could be the problem? i can force it to keep running just by feathering the throttle, but if i let the rpms drop a decent amount (about 600 or so i was under the hood not inside the cab couldn't look at the gauge) it will start to stall or just stall, it wont idle. maybe it is ignition timing, or fuel preasure, and the throttle is pretty responsive. i am pretty sure i have all of the vacuum hoses all in the correct spots. it runs rough to but there is no check engine light. any ideas are greatly appreciated thanks

First of all, a new or re-built engine cannot just be started and driven. It must be run-in and not allowed to Idle untill this process is complete.

Second its good to have someone dial in the timing while your on the throttle so that it runs smoother during the run-in....
