I dont agree , There is nothing stock about a 5.3LS with a turbo hanging on it , I work on the LS engines a lot and have to say that with all the work your doing a LS1/LS2 would of made about 100HP more with the same amount of boost , I have LS2 engine with bolt ons and tune doing 350HP to the wheels , add cams and 400HP to the wheels , add 4psi boost and he went to 667HP , you wont see that from the 5.3 with half the boost
The new 3 valve Ford would also been a good choise ,Have a stock engine 8psi making 500 to the wheels ,
Your choise of engine for a budget build (5.3 is cheap and easy to get vs LS2) is a good one , cant wait to see it running
