56 cu in horsepower rating:
If it's a 56 cu in bridged exhaust (86-92), then I believe all the blocks were the same, with the exception of 86 and 87 being permanent cast and 88-92 being lost foam cast. The horsepower rating was determined by cylinder head and carbs. If it's oval port exhaust (93<) I think the same is true.
