The longer one is for a raised block engine like a 413, 426 or 440. The shorter one is for the "B" big block engines like 361, 383, 400. I found this comparison which might be helpful.

I know I have a B block , my cast number is 2468130 , the description on Summit says it fits big block B , where you go to check the fit it has 383 big block B so maybe they need to fix their website .

Sometimes the description is incorrect, which obviously yours is! At least Summit has a good return policy! I would prefer to get the correct distributor but some have used a spacer to allow them to run the longer distributor in the low deck engines.
