Hey there guys! My name is Ross and I have a '66 GMC C1000 that I'm restoring. It is also my daily driver though, and a big part of my commute is I27 with a 75mph speed limit. I currently have a 305E with an SM420 and what I believe is 3.73 gears, but I'm on the lookout for a good deal on a 351E (Magnum). Anyway I know 3.07 sounds tall but I can work with it and need the mileage. I've found a few of these online but I need to verify that they will fit. Am I correct that my D44 is 26 spline standard rotation? What else will I need for this conversion? I do plan on keeping the Muncie for a while also.
