Default How much am I choking with my fast 78 on a 6.0?

I've been running a ported to the hilt FAST 78mm intake for a few years, and it seemed to really scream on my ls1, but i'm wondering if i'm being held back with my 6.0. I'm also still running a ported stock TB

I've been too busy grenading the drivetrain to worry about the intake, but now i'm ready.

my motor is a stock bore lq9, diamond 9.5:1s, eagle rods, stock crank. 239/242 .617/.629 114 bumpstick, CnC ported 5.3 heads.

my combo is th350 w/ brake, 4600 stall, 4.86 geared 9in.

car runs 6.90s/10.90s-11.0s right now, just seems that theres so much more in it. Infact I dynod it a while back and it only made 390RWHP, but I attribute that to heavy rear, short gear, and non lockup stall.

I really think I need to invest in a fast 90/90 or 92 to wake it up

professional thoughts?

well actually since yours was already ported id say prolly like 7-10whp for a stock 92/92 and maybe 10-20whp gain for a ported 92/92...
