Default 07 Yukon Denali XL build help

So here’s the run down

L92 VVT motor
Current mod is a k&n blackhawk CAI.

parts waiting to be installed
Mast L92 VVT ss cam
Morel 6504 lifters
CHE trunnion upgrade (like jewelry in a box lol)
hardened push rods
SS Intake valves
engine builder will decide which springs to use when he gets the motor.

So I hear different things about HI ram manifold vs short rams... I am interested in the Holley eFi Hi-ram manifold but people say that will only be good for high end power and not really help with the low end. Any thoughts ? Some even say hell just run the stock intake manifold...

oh and some 1 7/8 long tubes no cats open at the end of the y-pipe for now until I figure out the cutout situation.


Test subject

The stock intake is VERY good! Equal to the stock LS3, which is no slouch on its own! Either is good for up to about 550HP or a little more
