LT1 intake modding question
I have a few friends that are into import tuner cars and their over head cam heads have a bouble port like a Chevy head.To improve air flow cut the center vain to a knives edgeNow if you took a LT1 intake and removed the center vain and then cut the center avin in the head to a knives edge making the port larger would you improve performance or would it screw with the power balance

if I understand this correctly you would like to feed 2 cyl through one large runner/port. I have never hear of this being done but I belive this would probably cause a flow imbalance. Plus It would effectivly reduce the intake runner length from 3.5in to about 0

The LT1 intake has very short runners. Most porting will hurt port velocity, and take away from your low end performance. I've yet to see a ported LT1 intake with a documented HP gain.
