1992 z28 engine swap qeustions
I have a 1992 z28 with 305 tbi motor. I bought a complete 350 tpi motor with wiring harness, ecm, and pass key box off a 91 z28. Do I need any other parts to complete the swap ?

If your chipped key is working properly you should not need the pass key box. If you do swap it out you may have to change your key chip to match that box.

I have the key and the pass key box from the 350. I didnt get the ignition cylinder from the 350 though, cause the person I bought the 350 motor didnt pull it

Re: 1992 z28 engine swap qeustions
another issue you will run into is the speedometer. the stock tbi uses a vss buffer. the vss signal on the transmission is 2k ppm and goes to a vss buffer from there it sends a 2k signal to the ecm. I am unsure if this is a optical or magnetic signal but you could try to run the buffer pin c tap off of that to pin b10 on the 1227730 ecm. The last few swaps I did I just reprogramed the memcal to a optical and used pin c6 on the ecm and use the optical feed from the buffer pin F. Another option is to get a 90-92 camaro vss and wire it directly to the ecm and the ecm has a buffer in it to feed the speedometer and cruise.
