That '66 426 Hemi should have solid lifters, is that the route you are going?
All I "thought" I was waiting for to install a RMS StreetLynx or Gerst triangulated rear suspension was the money and having checked off a couple of more important boxes, like my QA1 K-member and front suspension and buying the Wilwood disc brakes, and getting it all installed. Well I've bought the brakes
and when they come in, I'm ready to get all that installed. So I "had made my decision" and it was a question of RMS of Gerst...that is until this thread. I will ultimately do what I want with my V-code car, but the performance and relative ease of adjustment of the Caltracs suspension was the selling point AND the full reversibility was a bonus.
In your case, reversibility isn't a factor in my opinion.
