Default Starter Issues

I am having issues with the starter on my 350. I have tried both a mini high torque starter and a factory style starter. If I just bump the ignition enough to start it it will idle fine. If I start it without bumping the ignition or if I blip the throttle, I get a loud screeching sound from the starter on the flexplate. I have tried mutiple shims with no change. I have also checked my wiring to make sure I only have signal to the starter on crank and not on run. Any other ideas? Also, I should add that the stock starter was on this engine when I first bought it and this wasn't an issue. Could I have a bad ground causing the starter to do weird things with a voltage spike, or ????? I 'm lost on this one.

what starter do you have in it now? if it's an older starter the solenoid might be sticking and or the bendix doesn't return properly. i'd be better to help you if i saw the vehicle in person.

Do you have a ground wire going from the battery to the engine block? It should probably be about a 10 gauge wire. If you do then it shouldn't be a ground issue. To make sure it's not a problem with your ignition switch wiring disconnect the ignition wires on the starter and use a remote starter switch. If it still has the problem it's not the wiring. I wouldn't think it is the solenoid if you've tried more that one starter. Are you sure the flex plate is bolted on tight and not bent?

Thanks Kodiak450r for the help troubleshooting this today.

I found by process of elimination that I made an error when wiring the alternator. The alternator was spliced into the crank circuit for some reason. I think when I would run up the RPMs the alternator would power the solenoid enough to engage the starter. Works great now
