Good point, very possible. Really makes me wish I paid better attention when I bolted the V8 one in.
I went and looked that old k-frame and it kind of looks like it could be shifted based on the witness marks the washers left. Time will tell.
I also grabbed a quick measurement of the crank CL and I am right at 1.125" offset from the DS, it is supposed to be 1.25". So I am 1/8" too close to the DS which (I think) matches the way it seemed the k-frame needed to go just based on alignment of the ends of the k-frame legs and the outside of the frame.
Guess we will see soon, it will be the next thing I mess with when I get back into the shop this week.
