Описание к видео LS 4.8 5.3 6.0 Cathedral port Intake Porting 615-183

Dorman 615-183 Tall 3 piece truck intake. I discuss a casting issue that restricts the cross section at the intake to head openings. Dorman restricts the opening of the intake port by 20-25%. By removing/blending the stepped protruding area flow can be improved/restored.
It’s plastic so go very very slow it’s unforgiving!!! 😉
