Heh Matt, how do I get a hold of you brother? I need to pick your brain about tuning these LT4s .

Great video 👍

[@eddielewis3868]

or is there a way to change the air flow sensor that your talking about on the g8 gt to get better air flow cause i’m waiting on my 416ci long block to get delivered now

[@ApeMotorsports]

It requires a custom tube from the filter to the throttle body and a jumper harness. The ls3 maf has a different plug.

[@eddielewis3868]

what intake would u recommend for a N/a 416ci for the best air flow on a 102mm throttle?

[@ApeMotorsports]

Roto-Fab sells a high flow version that is a full 4" tube and accepts an ls3/ls7 style maf. They also sell the coupler to go to a 102mm throttle body. You also need a jumper harness to adapt the maf plug on your cars harness to a ls3 maf. This will require custom tuning once installed to run the engine.
