Does an LT1 starter need shims?
 

I have an LT1 starter on an old 69 block, I hit the key and it clicks once. Does it need shims? My voltage is good.

Sometimes.

Try it and see, you don't even have to take the starter all the way off.

Turned out to be an electrical issue afterall, once I got that fixed, it cranked over just fine. No shims needed.
