I have searched a lot and can't quite seem to find a definite answer to this question. I have a 95 z28 that is knocking and I found a 93 motor for cheap. What all do i have to change on the motor to put it in the 95. Would the intake take care of everything? I know the opti is nonvented but are the plugs the same?

I don't know if it matters but the 95 z28 is a six speed and the 93 motor is automatic.

 

The basic long block is the same. Swap over the intake and exhaust manifolds and the OPTI, timing cover, timing set from the front and the knock sensor and you should be good to go....

Oh yeah, the oil pressure sender is on the side of the engine on the 93 adn on top of the block on the 95. Swap the 95 sending unit over to the 93 block and put a plug in the hole on the side of the 93...
