I've seen you post this a few different times... 7730 cars have the ESC built into the ECM. Also not sure about removing a used KS without damaging it. A Delco replacement is $41 from Rock Auto, is there something wrong with a currently available replacement?

PS 89irocz355, please check your email, and PMs.

Re: Parting out 1991 z28, 5.7tpi

Thanks, I just got a pm about it as well. I knew this but some reason It doesn't stick in my rock. Mental block and getting old sucks

I'm used to the maf cars but for this 92, i'm going 305 tpi to 350 tpi, haven't looked to see if the knock sensor or the esc are setup the same for both motors?

I'm sure someone will correct me if I'm wrong, but the knock sensor and chip are specific 305 vs 350. I'd imagine a person could have limited success running the complete 305 complement of parts on a 350, and leave the computer thinking the car is a 305. But it'd probably work better to use a 350 KS and chip.

I'm in a similar boat. I've got a complete 305TPI 5spd setup, that's going to go on a 350 with a T56. Neither stock setup is going to match up completely, but a 350 setup would probably be closer... IDK neither is ideal, fortunately I've got a long time to think about it before I'm ready to start the engine.

Re: Parting out 1991 z28, 5.7tpi

Your right knock sensors and knock filters are frequency matched off cid.
The 350 Memcal anjf,aujp etc would be the best to use with the 350.
It can be reprogrammed for Bette idle rpm iac control when using it with a manual transmission.

How much for the 2 wire harness that connects the coil to the ignition control module under the rotor on the distributor? I believe it is the plug on the coil closest to the firewall. Shipped to NJ.
