Default Keep stock t6 or swap to t4 on s475?

Wondering if I shod switch to a t4 flange and housing on my s475 instead of using the stock t6. The onl reason I'm considering this is for quicker spooling. What do you guys think?

It's a stock 6.0 gonna do a little port work on the 317s and hopefully get a jfr custom ground cam. Stock truck intake. Air to water intercooler. Going to have a tubular header on drivers side that crosses over into a log manifold on pass side. Goin to be 2 1/2 hotside

Manual or auto? Honestly I would go with 2.25 pipes in a divided configuration and keep it t6

It a 2 speed powerglide. But that's something else I'm debating. I saw the black nova in fsc that ran 8.3s with a crossover and log manifold and hougjt it would be a good idea

Yeah for a 6.0 with an auto, unless you have the WRONG converter and cam it is going to light off plenty quick.
