Need opinions on a wild 4.8L setup

[62nalide]

Ok here are the dyno sheets one this 09 4.8L RST, 1st one is NA specs custom grind (specs can't be given by vender(venders policay) 1 3/4" long tubes, dual 3" with X-pipe, 3200 stall, UD pulley, MSD wires, and K&N intake the second sheet is with nitrous so the plan is get the 243s ported and polished and a vic jr inatke with an elbow will it be ok or no? it will be getting 4.56 gears and a 3600 circle d stall please share your opinions please what would be a good thing to do. Thanks

Honestly think that the 4.56s would be too much gear for a 4.8 unless your planing on having big rims....stick to some 4.10s or 4.11s n preferably i would go with a yank stall instead of a cirlce d..

ok ok, these NNBS RSTs come with 22s on a 305/40/22 reason 4.56s came to mind was most people say they wake these heavy trucks up but will consider those 4.10/11s

id go holley high ram , and spun the fug out of it

Go higher then 456 and go least 1k more in rpm on stall if ya want it to move out. Holley intake is where its at

[RS/SS 4.8]

4.88, holley high ram, 4k stall. Sounds like fun.

Yeah its a weekend and would like to drive it on the highway at least 2 times out of the week, so what about porting the heads and the holley intake with the 456s and 3600 stall? No bueno? The truck is a crewcab fyi lol

[Frenchy]

Never mind porting the heads. For a what a set of CNC ported, milled brand new heads cost now, I don't see the cost effectiveness. Unless you know head porting like the back of your hand. And 4.8s love to rev, in a heavy ass crew cab you're really gonna have to take advantage of that. Lots of gear, lots of stall, spin the piss out of it.
