It depends...

The bell housing needs to match the SBC block, should bold up to the 700r, not sure about the drop on the T-Case from the S-10, I thought those were pass side drops.? Anyone????

On the computer, are you running carbed or FI on the SBC? If carbed, no your YJ wiring is fine, just need to splice int he new ignition module and sensors for the chevy motor. If FI, you'll need a harness from painless wiring or somewhere, or a decent donor harness from the rig the SBC came from.

Match the harness to the donor motor, not the Jeep.

I'm assuming the SBC was not out of the S-10.
