so do you think a carbed cam on the drivers side will work with a spfi cam on the pass. side?

The SPFI engines use a very different ignition timing curve than the carb ones. I believe that that is partially due to different cam timing/profiles. I'd be very interested to know the actual specs for each of the EA82 cams.

The first is the basic engine specs which include the cam timing, the second is the lobe heights along with how to ID the different cams. It turns out that CARB and Turbo use the same cam. This info is from a 86 FSM

The left cam has a gear-end that meshes with the distributor. The right cam is shorter and has no such part.
Technically, yes, the carb and turbo cams are the same, SPFI and MPFI are the same. But believe me, you can swap back and forth between them all with no problems. And you'll never be able to tell the difference either.
But left to right or right to left...ain't happenin' :cool: \
