Good morning! I'm looking for input from anybody who is successfully running one of these on a SBF. I have read very little about the XF-8 (or the XC-8 for the SBC). I'll be running this on a mild stroker in a hoodless / fenderless Model A street rod. The carbs are mechanical secondary 450's. I am custom spinning a vacuum log (ign., PB,...) and will install between the carb spacers to provide some balance between the separate plenums. I realize that there are plenty of easier or less problematic intake choices. I'm obviously after the curb appeal running something you don't see too often. If you have any input on how to make this work well please post.
