I believe my dyno is about 1991ish but I know it has the 833 absorber. Im pretty sure his is newer than that.
Saying that, does that stand look like it will have header fitment issues? On mine, there were two legs that support the absorber that were vertical and too far outboard.
I used some round tube and moved the bottom in as far as I could and I haven’t found a head that won’t fit.
I was having dinner with Troy from westech tonight when I read that. He said they use Schoenfeld sprint car headers on just about everything and almost every other header needs to be modified to fit the stand.
