I have a 87 Iroc-z Camaro, with a 305 TPI, i want to put in my 88 Iroc-z Camaro 350 Tpi engine, after i take my 305 out and put the 350 in its place and hook it up, what else do i have to do for everything to work right?

 

Change the knock sensor, unless the 350 already has one in the block. The injectors are 19lb. for the 305 and 22lb. for the 350, Put in a 350 chip and that is it, I can't think of any other differences. If you have not already done so, I would suggest porting the plenum while it is apart.

Well the 350 TPI came out of my 88 Camaro, the car worked great but i got in an accident, so i need to take the real good parts off my 88 and put them on my 87.

I am not sure what the knock sensor is? but if it is bolted on the 350 engine somewhere then its on there?

About the computer/chip is that real hard to change i am not very experienced with cars yet?

 

It's pretty easy. Just pull down the computer, take out the two screws holding the small cover on, and swap the chips.

 

As far as the location of the knock sensor, it's screwed into the side of the engine block on the passenger side just above the oil pan about right in the middle. I'm sure you have the right one in your 350 already, so all you have to do is just plug it into the wiring harness. And yeah, the chip is really simple to change. Just remove the hush panel underneath the dash on the passenger side. The ecm is mounted behind the face of the dash with one or two screws(7mm). Just like the other guy said, remove the little cover plate on the ecm, pluck out the old chip, and plug the new one in its place.
