i recently switched my manual 350 3/4 ton chevy to an automatic with a 400 turbo. it started a bit rough, like the starter needed shimmed, and i put it off for awhile. finally my luck ran out and it wouldn't start anymore. funny thing was that the starter just stopped working, it was like the starter was pulling too many volts and draining my battery. i have replaced the starter and battery (one that has 780 cold cranking amps, more than enough) and it still won't turn over. as soon as i hit the ignition it shoots the bendix gear out and it gets stuck in the flex plate teeth. i've tried shimming it any way that i can think of, but to no avail. the teeth on the flex plate show some wear but nothing too severe. its really getting frustrating
. if anyone has an idea on what the problem may be let me know...im open for any suggestions!
