Does a 1988 4.3l tbi z motor have the same cam as 1993 4.3l z motor?

Are the 4.3l tbi z motors from a 1500 pickup the same as the ones in the s10s?

Thanks, Cory

Pretty much except on the 1500 it has slightly bigger injectors.

So an 1988 s10 z motor is the same as a 1993 s10 z motor? Why do the pickups have larger injectors for the same motor? wouldn't that cause the engine to run rich?

The injectors are larger and the ecm programming is different (see flow rates).
