As a guideline I would say to avoid boring into any bosses and especially the bolt bosses that hold the cylinders to the case.

The largest you can go on Shovelhead cases is 3 13/16.
96" is 3 5/8 bore with 4 5/8th stroke.
If you where going the biggest with that stroke crank you would get 106"

My shovel has 3 5/8" bore and that cuts into each side of the center case bolt by about 20%............but with a 4 3/4" stroke plus 020 over cyl, its right at 100" and has held up fine for 30 yrs.

I bet that old bitch vibrates like a sum bitch!

A guy told me once not to own a shovel unless you have a good dental plan.

But you got to love em.

Vibrates so bad over 75 mph I can barley hold on to it!!! And it's been balanced twice using S&S rods. It's the main reason I built my softail!

That's how I got some women in bed back in the day. If my bullshit didn't work I'd put em on the old 62 Pan and that 2 wheel vibrator would loosen em right up.
