From MoparWiki this is a bunch of Miss information as to the camshaft and the crankshaft.
Engines
EH1 360 High Performance Chrysler LA small block based on the car division E58 police engine with upgrades. The upgrades included a 68 340 Chrysler LA small block camshaft with a 276 duration, .484 lift and 48 degree overlap. Then a double roller timing chain and gear set was added for durability. A set of 360 high flow heads featuring 1.88/1.62 valves helped moves gases in and out. It used a forged crankshaft with 8:4:1 flat top pistons and featured a bore of 4.00 inches and a stroke of 3.58 inches respectively. It is also believed the rocker arms and springs are more heavy duty than the standard E58 pieces used. Also, Chrysler topped the package by using a 850 cfm Carter Thermoquad 4bbl carburetor with bigger primaries and secondaries than the police version of the carburetor. The engine was rated at 225 hp @ 3800 RPM and 295 lb/ft of torque at 3200 RPM.
Note: The prototype Lil' Red Express used W2 Cast Iron Heads, Holley Aluminum Intake, and Holley 4160 4bbl carburetor. Again, this was only the prototype and not the production version that featured this items like some people believe.
