The heads are PN P4529336 bare-aluminum heads from Mopar Performance. Bare heads were used because Richard presses out and replaces the valveguides so he can achieve the correct stem clearance with the chosen Ferrea or Manley valves. The heads also receive a complete valve job with bowl blending and stage-one porting. Then there are the Comp Cams titanium retainers, Viton seals, and head machining for the use of spring cups, which Richard likes better than shims. With this combination, installed height modifications and special street roller valvesprings are used. Stage-V polished-stainless-steel roller rockers that the top fuelers use are employed. For street use, Richard makes sure they have the extra oiling provisions for the pushrod cup. Rocker supports are from Mopar, and the pushrods are custom length, with hardened thick-walls from Smith Brothers. The oiling system is all Milodon, with a high-volume pump and the special windage tray for stroker motors.
The Intake manifold is from Indy Cylinder Heads, but Richard also makes his own. He welded the oil filler and the Mopar logo breather onto the Valley plate so that the Stage-V polished valve covers would stay clean looking. The sequential EFI system and electronic distributor are from F.A.S.T., and Richard likes to use the MSD 1,000-cfm throttle body. The injectors are 48-lb/hr ACCEL units, and the spark plugs are Champion RN12YC with extension modifications. Resistor plugs must be used in this configuration.
So, what Mopar Engines West has done is to fill an old-style Hemi with accessories to bring it into the 21st century. How hard was it to dial-in, and how did it fair on the dyno? You'll have to tune in next month for the results.
