I put a beefed up383 strokerand 350 turbotransmission in my 92 silverado and had it turning over trying to set the timing when it just stopped turning the motor over im frightened that I locked it up but the motor was ran once to be dynoedand ran fine and the motor didn't even fire when i was trying to set the timing can any one help me outI would be very thankful.

 

sounds electrical. check your fuses and ground, starter, starter relay, etc. Do you have any electrical power?

 

Yeah it has power, the starter engages but doesn't turn it over but I have more than enough power from the battery.

 

are you sure its engaging? and not spinning without engaging? pull the starter and test it to see if when its hit it spins and actuates.

 

Yeah you hear the starter engage and it just doesn't turn it over I was told to barr it over myself and im going to try that to see if I cant bust it loose or find out what is ceased.

 

also make sure the teeth on the ring gear are not worn off, maybe you hada misalignment issue and damaged it.
