I know most die hards on here dont like the crate motor classes in IHRA but you could "BUILD" a similar combo with a Duster or Demon for I think "C" or "D" crate motor class except without the 3X2's combo (limited to a single 850 CFM carb as per the crate motor rules for big blocks). The engine has a little more cam than a six pack and bowl blending is legal in the heads (eliminates the cheating and trying to hide it) The combo was developed by Jack McCormik (sp?) back when MoPar did not have a factory produced Big Block combo at that time. Maybe thats where he got the idea? There were at least 2 of them running several years ago (10 +) and they ran well without the combo being on "Kill". If anyone is interested in building such a car Im sure Danny Waters or Hank Blankenship could help out with the complete specs. It makes a fast low dollar combo for those who are not overly loaded with money.
