FYI dual quad for early 273 on eBay
as stated OFFY still offers a complete line of early 273 intakes, they will make any thing they have a mold for,,,last i knew,,they were still old school no web site or computers,,, old fashioned phone ordering or thru a distributor,,,i believe jegs or summit can also get parts from offy
about 4 years ago or so i had off valve covers made they told me they had not made small block mopar finned valve covers in many years,,,still had the mold so they popped out a few sets,,
