this is the 522/525hp version from CME. It's a very mild build but the combo would appear to pretty well maximize the 440 Stealth heads as delivered. They offer much hotter versions as well. This one would make a pretty good truck engine
Or, work well in a Challenger to putt around in traffic on a hot day with the AC blasting.
“CHRYSLER 522 STROKER"
522 PLUS HORSEPOWER
HIGH PERFORMANCE PUMP GAS STREET ENGINE
CAROLINA MACHINE ENGINES uses the highest Quality brand products including: Clevite, Cloyes, Comp Cams, Corteco, Dana, Eagle, Elgin, Federal Mogul, Felpro, Hastings, Lunati, Manley, Melling, Perfect Circle, Pioneer, Probe, RHS, Scat, Speed Pro and Victor Reinz.
Except for the seasoned and sonic tested 440 Chrysler block, this engine is all NEW. The short block assembly is equipped with a forged steel 4.25" “Stroker” crankshaft, 4340 forged steel rods, Keith Black forged pistons, moly rings, brass expansion plugs, and performance bearings.
The longblock is further equipped with the STEALTH aluminum heads, 2.14/1.81 stainless steel valves. It has performance pushrods, valve springs, roller rocker arms, hydraulic lifters, and a camshaft with over .510" lift and 280/230 duration.
It is expertly machined, balanced, blueprinted, plate honed, line honed, and decked. It has been assembled by a highly capable technician and spin tested to check the oil pressure, compression and oil circulation!
To the complete versions are added the oil pump, oil pan, oil pump screen, timing cover, harmonic balancer, valve covers, dual plane performance aluminum intake manifold, oil filter, oil filter adapter, dipstick, and spark plugs.
To remove the possibility of “New Engine Bugs”, our complete versions are then dynamometer tested and “broken-in” with the proper carburetor, a performance distributor and quality headers and mufflers. The actual Dyno sheet from the Dyno printer, not a copy or generic, is provided with the engine. A final crankcase pressure test and oil filter internal inspection is performed.
When used with the recommended carburetor, ignition and exhaust system, this engine will produce over 522 horsepower at around 5200 RPM and between 625 and 675 foot-pounds of torque at around 3700 RPM.
It will have approximately 10.0 to 1 compression ratio. It will have a “Choppy” High Performance idle and it will have fair manifold vacuum (8 to 12 inches).
We recommend a 1800 to 2800 RPM stall torque converter to realize the maximum potential of the engine.
