Default 1998 vortex 5.0 rebuild

Ok so I gernaded my engine alil while back so im in the process of rebuilding it fixing the issues I had like the head gasket and a couple lifters were sticking. So what my question is I'm already this far with it torn down I would like to boost my horse and torque what would you guys recommend that I could do to it I use it for plowing and towing light cars on a full size trailer but I would really love to not have to send it out to have the computer tuned or do you guys think of just cutting the crap and put a 5.7 in then my next question is it compatible with my computer and trans

Should be. The 305/5.0 liter was a dog back then. I'd drop a 350 in it in a heartbeat. You will have more HP and your gas milage will be pretty much the same.
