Intake Porting

Started porting an LT1 intake. I haven’t seen a lot of supporting data will see what it does.

Overall pretty happy with it ports are around 40.05 across and through the runner. Smallest area was about 38.25 straightened the ports slightly. Hand sanded runners with 320 then 600 to knock down composite. Hand sanded the throttle opening too with 320 and took some of the excess material out also. Time to rinse out the mess
