Recently picked up a '72 Cuda w/ a 440 and seems to be fully built, but we know very little about the car. Here are the mods I can see (having not yet opened up the engine):
Proform 950 carb
Weiand 7534 intake
MSD 6AL (Mopar) ignition box
Crane Cams LX92 ignition coil

We got it from a dealership that got it as a trade-in, so they were not much help, as far as what else was modded on the car and how it was maintained previously. What fuel should I be running on this bad boy? I was planning to use 93 octane pump gas

With what you are seeing and from teh pic in your gallery, I'd run nothing lower than 89 octane. Probably 91 would be fine though.

Did you ask the dealership for the PO contact or if they can contact him/her for you with your info?

I asked the dealership to give them my info and tell them I was interested in talking with them, but I haven't heard anything yet.

If you get the #'s off the block and the heads we could tell ya a little more and I agree with Tim, nothing lower than the 89. You may get some detonation and some knock lower than that octane.

i always run 93 in my 440
