Why I specified the use of a Vortec oil pan is because Vortec engines have longer bolts that are used to support the windage tray and I am unsure if the 87 and up pans have enough clearance to clear the longer bolts.
The main cap bolts that the windage tray bolts to are not long enough to affect the oil pan for any 87 and up engine... its fine, I used a vortec pan on My lt1 the main cap bolts for the windage trays are only slightly taller, plenty of room.
