IMO go with a 90 T/B
But for that amount of CASH I would get a carb style intake and elbow

I would think the 90mm FAST would hurt a stock headed 5.3. A 78mm might work pretty good...

search it on tech if you want, but ive heard that the FAST LSX intake manifold literally comes apart at boost levels as low as 10psi, id stick with a LS6 or go with a Vic jr. and an elbow.
