Yes they do. Although nowadays LT1 guys stick with the Melling Select pumps (10552 and 10554, high volume and standard volume respectively).
I used the 10552 high volume pump for my 383, but only because I have a modified oil system and a 7-quart pan.
A high volume pump for 90% of builds nowadays is not needed and just puts unnecessary stress on the oil pump drive gear.
