I have been running them for almost 20 years.Had one in a 63 421 HO.Raced it a few times with a 3.42 in the back and never broke it.I think the weak spot will be between the main drive and the cluster.I have one in my 421 62 GP right now.A guy at Richmond told me they have a 20% fudge factor on their ratings.I think a iron case and mid plate will help.Worst that happens is you break it!Tom

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
