90 RS 3.1L V6 MFI to a 5.7L V8 TPI
I have read the posts about v6 to v8 but since I have fuel injection switching it over to a v8 looks like a strenuous task and I want to get it done but needs some help please help me get prepared to make a step in the right direction. Any suggestions feel free to leave any.

Welcome aboard thirdgen.org.
Do you have a donor car, or are you buying the TPI engine and pieces separately? Complete engine and ECM harnesses are highly recommended.
There is nothing particularly troublesome going from EFI to EFI. In fact, it could be argued that it is easier than going from/to carb/EFI. You will have to drop the fuel tank to replace the fuel pump, but, it's basically an unbolt/bolt up proposition. Some bolts are a little harder to get to than others, that's all.
