***LMR Proprietary Gen V LT1 CNC Porting Video!*** Here is a video of our Proprietary CNC porting program being run on a fresh set of 2014 Gen V LT1 cylinder head. Our porting program picks up the airflow of this cylinder head by 45cfm over stock at .650 lift on the intake and 42cfm at .650 lift over the factory exhaust port at 28" of water when flowed on a 4.060" bore.
Our before numbers were as follows:
Was flowed on a 4.060 bore at 28" of water with a Untouched port and valve job.
lift Intake Exhaust
.200 134 120
.300 204 164
.400 258 193
.500 291 204
.600 285 208
.650 291 210
And are after numbers are
Lift Intake/Exhaust
.200 137/116
.300 208/154
.400 270/197
.500 310/228
.600 331/245
.650 335/252
.700 340/257
.800 345/260
Still have quite a bit more development to do, this was first attempt. We want to see how these act in the car on the dyno before we make any changes though.
