"Next Victim"

Something changed from the earlier pictures? Looks like the bypass valve was electronic in the first pictures?

What’s the back story?

Just curious.
the upper pictures (post 279) is a DSR 1150 which is slated for Graham Rahall and on display at the HP Tuner tent @ Holleys Moparty event, the last two is Butch's "Big Red" in my shop.
