Just a thought, why not line bore too 2.498" and use the 81A bearings? If I did it, I'd bore it 3 3/16" and use 8BA rods and bearings. Sure this would be a chunk more cost effective. Yes the 21 stud crank is lighter, would you be able to feel the difference? I doubt it. With a welded and stroked 21 stud crank, you wallet would be considerably lighter!
Now about these Sharp 21 stud heads?
