Hello everyone. I am new here

I own a 93 Safari with the CPI 4.3 and was wanting to go to a v8 w/o much effort
I was wondering what year 350 would drop in w/o having to get a complete wiring harness

Im looking into a CPI 350 or a TB either way, and was told i could just use my old computer w/ a new chip in it from the donor vehicle.

Can anyone steer me in the right direction?

Im aware of having to run electric fans and such

Also, what motor mounts would I use? Im assuming the same as the 4.3
