Stubbs, where are any pictures of your car? I would like to see it.

@shaun65Polara where in Minnesota are you? I'm at the bottom of the state. Wow is all I have to say about the engine compartment, didn't expect that from the profile view! I like **** being wrong for all the right reasons, so you're good in my book. Looks like you enjoy the car and drive it often. A big Hell Yeah to that!
ok

Yes I am.
im running a stock convertor & the replacement valves springs that was used on the 383 magnum,440 magnum & 440 six pack motors . the b/rb/six pack cam needs the stiffer springs for the valve train to work right (I have the old mopar performance racing catalog & the big block racing book (I have the cd its the same was the book)
 
Where does this cam deliver optimal performance? I see you towing a trailer in a pic or 2, and wonder if this cam would be the thing for me. Do you know how much power and torque your 440 produces at given angular velocities? (rpms) I've been exhorted toward "purple sticks" by a couple local enthusiasts, so your cam particularly interests me. I saw on Summit this cam is the "Six Pack" 375 HP cam. If this is so, it makes a good engine, but not really what I want.

Lovely NYer too, BTW.
