So I just finished swapping the 305 out of my 84 Caballero and replacing it with a GM Performance 350. I am using the stock flexplate along with a smaller starter to clear my headers. The starter was on my old block with two shims across the top of the nose but when I put it on my new block I used no shims. Currently the bendix gear on my starter sticks too far out when it is not engaged and it interferes with the flexplate. I have asked countless autoparts store employees and no one has been able to help me. I have bought new starter bolts, tried all sorts of combinations of shims and have had no success. If someone could help me out it would be much appreciated. It been four months since I've hit W.O.T. and I am beginning to have withdrawls. Thanks for the responses.
