L98 motor swap into 1970 Chevy C-20 4X4

I picked up a l98 motor and am going to swap it into my chevy. I have a couple questions.

I want to get rid of all the emisions on the motor since i dont need them any insight on how to plug or cap off wiring?

Also wiring harness with computer where would i get one as well as motor mounts.

My transmission is a 4 speed trany with Grany gear would i match the clutch up with the trany or the motor.

Any insight on the swap would be great. Im am going to do the swap in my garage and want to get all the parts i need before i start. Thanks

Well, we are a 3rd gen f-body Board. Rules say topics have to be related to 3rd gens. Having an engine out of one might qualify if the can be related to 3rd gens, but you're going the wrong direction for that.

But, a will answer the emissions questions (you still need O2 sensor if you're keeping the TPI system), and most any small block Chevy can be mounted to a Chevy V8 bellhousing. I'm afraid you're going to have to figure out the flywheel and clutch yourself (hint: 1-piece rear main seal and 168-tooth flywheel).
