Hi guys, Im new here and i need help. i have a 91 camaro with a 350 tbi. im assuming the engine came out of a truck because it has the 4 bolt main but i have no idea what truck and the starter went and im lost now.
Any and all help will be appreciated im not sure if the pictures help at all

 

Most Chevy starters interchange as long as they have the right nose for the trans. I've even put a starter off a small block on a big block. Just take it off and go to the parts house and get one like it or better yet get that one rebuilt at a shop to be sure it fits right, sometimes they need shimming because castings vary quite a bit. If you're lucky a rebuilt from a parts house will bolt right in and mesh with the ring gear just fine but sometimes they can be a problem,small block 400's always seem to be a problem with starter fitment and that's where I learned the lesson to get the one off the motor rebuilt rather than replaced.
