Apparently those are Angus Street Duty rockers. May have been an Early Scorpion partnership or...? I don't see any info after 2008, but some F**D guys claimed to have run them for many years. I've run Scorpions on a couple engines--cheap and never had a failure.
They are most likely Scorpion Rockers. They have private labeled them for a LOT of different people!!!:yes:
Speedway, Competition Products, Summit, Trick Flow, Hanlon Motorsports, Anderson Motorsports, etc.....Just to name a few...
I've run quite a few different sets of Scorpion Rockers.:yes: Lots of mild street stuff and a few more extreme setups...over 240#'s on the seat and well over 600#'s open.......never had a problem.:no:
