And polyFrom google pics I think you might be right. Looks like it might fit the early hemi too.
Yep that's why I just modified my point dist to use a later inboard arm. It advances and returns consistently so it's working, correctly or as preset by the factory pffffffttt who knows. I have way over 50° at cruise which keeps my rings alive, and returns in the teens on the highway. Definitely needs some fine tuning but the carb is a loaner, when the TQ goes on in the spring I will be dialing it in.Thanks for the info. And I found out how hard the canisters for the big blocks are to find at a reasonable price. It took me 3-4 months to find one that wasn't $60+.
