Stock 5.3 short block (rod bolts, head studs, mls head gaskets, stock 799 casting heads with good springs, retainers and locks, ls6 cam, comp lifters)

stock manifolds front mount and a 85mm turbonics turbo

?????? 750 to 850 flywheel ????????? with a very safe tune (very low timing)

 

Its possible with the right tune. Car craft did an article on a stock 350 that was boosted it was a 9 second car and the ls series motors are built better so its definitely possible.
