Default What intake? Lsxrt or holley?

Okay first things first I'll tell you my set up. I got a 01 rcsb with a m12 t56 with the 2.97 first, .56 sixth, 4.56 rear gears, nitrous, and a 5.3 right now. I have a forged 370 on the stand waiting on some pushrods then I should be swapping it over within a month or so.

The 370 consists of
6.0 block .030 over
Stock crank
Compstar 6.125 h beam with arp2000 bolts
2618 wiseco flat tops .022 top ring .024 second ring
799 heads hand ported
234/242 .629/.629 112+4 then I advanced it 2 more degrees
Morel 5290 lifters
Harland sharp roller rockers 1.7s
Tbss intake with 90mm tb

I'll be spraying a 150 shot at first. May bump it up to 250 eventually. I really like the hi ram but want to keep some lowend power so that's why I kinda thought about the lsxrt but I've heard horror story's of them leaking. I take it to the track 5-10 times a year but this is my daily for now. I'm sure I'll get a gas getter later on. Right now rev limiter is set at 6500 but might raise that to 7000 later on. What intake would you guys run?

Holley high ram for sure. Being a nitrous build heat soak won't matter and it will make power for days without choking it at high rpm. The FAst is a bitch to tune with a big boy cam. Not saying it can't be done but its tougher than any other intake that I know of.

I don't know if this matters or not but later on, like several years from now, I'd like to throw a procharger on it. The motor is 11:1 right now but I can always swap a set of 317s back on it to drop the compression some. That's if I can get the heads off in the truck with the head studs. Keep the answers coming guys
