What year is this 2000 spica engine?

[Kevin Trent <trentkc@xxxxxxxxxxxxxx>]

I am considering a '79 spider that is for sale.  Unfortunately it is an 
estate sale, the current owner knows nothing, and the car has no 
keys.  However, the Spica injected 2L engine is ALLEGED to be a replacement 
unit.  The engine's number is:  AR01615A96798.  The chassis number is: 
AR115.41.008945, manufactured 11/79.

Is there a web resource to identify the model year of this engine?

Thanks, //kct, Powell, TN
