The LT5 crankshaft design is somewhat unusual compared to most V8 cranks. Main difference is the lubrication of all main and rod bearings is done via interconnecting oil distribution channels drilled the length of the crankshaft. Main thrust bearing location is also different than most as is the ignition timing wheel reluctor slots that you mentioned. Consequently there are quite a few more precision machining steps required to produce a LT5 crank compared to a typical small block Chevy or others like it. To my knowledge there are only two experienced aftermarket suppliers still doing our cranks, Bryant and Moldex.
