Rick’s Sleeper 512 Mopar

December 25th, 2019

Long time customer and friend Rick, wanted something special for his Super Stock clone street car. This has been a great build, and has been the prototype builds for several customers since. The goal was a easily street driven pump gas combo with tire shredding power at any RPM. The 440 Block was bored to 4.375 bore, which is home to the custom Autotec pistons. Molnar 6.800 4340 H beam rods tie the slugs to the Molnar 4.250 Crank. Total Seal AP Steel rings seal the deal. The cylinder heads are CNC ported 440 Source units, with 2.140/1.81 valves, and Max wedge openings. This same CNC port is the one used in our 440 aluminum heads, as well as the Edelbrock RPM heads, so this performance is available to anyone with any of these style heads. The hardware in the heads is all matched to the custom hydraulic roller camshaft. Pac Springs, locks and retainers work great to keep control of the valves as the RPMs rise. The camshaft is only 243 @ .050 on the intake side, so this combo is pretty docile until the loud pedal is smashed. One particularly cool aspect of this build, is the dual plane Indy intake manifold with the Holley 950 Carb. The manifold is an absolutely huge dual plane that kind of looks like the old CH4B Edelbrock on steroids. Match this with a Max Wedge port window, and there is power available everywhere, as well as a subtle look. Rick’s is devoid of any logos, and is painted engine color for even further sneakiness. As far as power goes, this sneaky big block Made 682HP and 688lb/ft of torque on 91octane pump gas. According to Rick, the car is an absolute riot with it’s A833 4spd, Ram dual disk clutch and 3.73 gears.
