im using a mopar performance b/rb restoration cam its 383/440 Magnum the only one they r currently making is the "3 bolt " cam the specs r 268-284-46* with a valve lift of .450/.458 it has a centerline of 115 degrees the old part # of the cam is P4529270 summit racing lits as Mopar Performance Purple Camshaft Kits P4529270AE $428.99 u wil need valves springs good for a .500 " lift cam .i have this in my 1972 new yorker it has a 72 440 rebuilt to 1971 specs here r a couple of pics of the car & the motor
what dose it weigh? a heavy car should only have a 2000 stall in it . a 2600 will run out ok a stall convertor has to be loaded (brake torqueing it )
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.
