5speed

Just bought a 92 s10 2wd with the 4.3 5 speed. Looking to install a 5.3l I have laying around and was wondering if the factory t5 transmission will work with the 5.3. If so what modifications or parts would I need to make it work?

I bought a 1992 Extended cab S10 With the 4.3 and a 5 Speed And was wondering how to identify what transmission it is and what the gear ratios of it are thanks
