The Callies Dragonslayer crank (3.875") will that connect to the stock LT1 crankshaft hub ? , and what is the difference between the LT1 crankshaft hub (part # 12553250 ) ,
and the LT4 crankshaft hub (part #12550097) ?

stay safe

Nope, this is more of a LT1 Tech question.

Yes. You will need to use either the LT1 specific notched key if using a stock damper hub, or you will need a keyed hub.


>what is the difference between the LT1 crankshaft hub (part #12553250), and the LT4 crankshaft hub (part #12550097)?

P/N 12550097 is not a LT4 specific hub. It's shorter to accomidate the crank trigger used on 96-97 LTx OBDII engines. P/N 12553250 is for 93-95 OBDI LT1 engines.
