I am building a 440 for my 74 club cab long bed that will be used occasionally to tow a trailer with a car or tractor.

78 motor, 452 stock heads, cast crank, rebuilt oem rods w/ arp bolts, stock 71 pistons, hooker comp headers w/ dual exh and flowmasters, compression around 9 to 1. Hughes cam:
Hughes HEH1928BL Camshaft
Intake Valve Lift 1.5 .489
Exhaust Valve Lift 1.5 .524"

Intake Duration at .050" 219°
Exhaust Duration at .050" 228°

Lobe Separation Angle 111º

Intake Opening at .050" 1.5° BTC
Exhaust Opening at .050" 48° BBC

Intake Closing at .050" 37.5° ABC
Exhaust Closing at .050" 0° ATC

I will be using a 4.10 gear with 30" tall tire, and upgrading to 518od at some point. Plan on using an 850 Thermoquad. What intake should I get? Read that Performer is basically an aluminum copy of the oem cast iron piece. Is the Performer RPM a better choice? Any other suggestions?
