If you decide to go LS7 route, Frans96SS would be a great choice to do the work. But, you can accomplish same power or more, if you simply add a TVS2300 or TechCo S/C and a set of LT headers on your existing engine and will cost you a lot less and headache free. If you're planning to race, could then build the LS3 and the tranny along the way. But for DD, and normal street driving, keep it under 600 RWHP, before breaking things.
Hope this helps!
Oh btw, if you start going into new engine, you need to save up a lot more money, because you'll need it or your car ends up sitting in a shop unfinished for months. Trust me, I've seen it!
Do your homework first, find out every thing you need, how much for the parts and labor and shipping, before you let someone touch your car.
