No part #, but I'd be interested in finding out if the cam was the
same between NA and turbo versions.

My book says (NA only available here):

                    Opens     Closes    Duration
        Inlet      23 BTDC    71 ABDC     266
        Ex         60 BBDC    53 ATDC     276
 
        Valve overlap 58
        Rocker ratio is 1.642:1

I've got a service manual supplement with the 1227808 ECU stuff, and the
changes from the previous model's motor (that used Bosch LE-2 Jetronic).
