what would be different between the 93 to 94 and up?? I found a 94 z28 rolling chassis thats in great shape,what would all need to be changed to put my 93 speed density drivetrain in the 94 chassis?

 

shouldnt be too bad if you still have the wiring harness, computer and such from the SD car, if you dont then that makes **** exponentionally worse

 

ill have everything, im just curious what extras I would need or the differences ill come across

 

I would recommend using the PCM and wiring from the 94. You will need 94+ O2 sensors and take the IAC connector from your 93 harness and use it on the 94 harness. You would also need to have the PCM reprogrammed to work with your old engine. You can keep it SD too if you want.
