Installed on a 350 in a 1980 corvette with a huge original style failing starter and headers running close to the starter. I had to clock or turn it one notch because it was hitting the engine block. After that it fit perfect with no need to shim. Instructions say they don't recommend any wrap, but I put some on because my headers are so close to it. So far so good. Not getting any lagging like I was getting with the old starter. Very strong.
