Thorley BBC header ID help
Thorley BBC header ID help
Can you help me identify the application of each of these? I have 4 sets. And one set I had made into 3" collectors...

Re: Thorley BBC header ID help
303Y on one set
The one set with the O2 sensor is dated 8/98 The black painted header has a different 2 tube end arrangement prior to the collector. The black painted one must be an earlier release. I've noticed that the collector ring is 1 hole down, then 2 holes to the top
