I have an HEI that I believe is from a 350, but my parts books aren't new enough to confirm it. The part number stamped into the collar is 1103275 and 6J30. Can anybody confirm the application for me? Thanks. MArk
Mark, this is not a direct answer to your question but....if I remember correctly the 350 dist. will have a 14 tooth gear and the 455's will have 13 tooth. Of course these gears can be interchanged so the dist. can be used with the small or big block. Hope this is helpful o No:
