Hey Terry, if I remember correctly it was ss/p1 2-x4bbl
ss/p2 1-4bbl
ss/p3 2-2bbl
ss/4 was factory (nhra) SS
which back in the day was called formula ss.. I remember Dad running all of the classes , he a ran 427 in 68 coupe I remember those awesome looking braswell carbs sitting on top sheetmetal intakes ...pretty much the same looking intakes we run today in regular nhra SS
