So about a year ago I pulled the 305 from my 1986 Elky, and replaced it with a '68 327 that I rebuilt. The 305 was a 1 piece RMS, and the 327 obviously has a 2 piece RMS. I had to get a new Flexplate made for an 83 or 84 elky 305 to accomodate a 2-piece to my 2004-R. I have since gone through 2 starters, and now need a new one. The guys at NAPA had been telling me that any SBC starter made for 85-back auto tranny would work, however I just spoke with the good people over at NAPA and now I am told that there are different lengths that the Bendix shoots out to engage the flexplate teeth. My question is: What Starter do I need for my 68 327 at 10.5:1 compression? Any help would be much appreciated. Thanks.
