look at the article's pictures of the head design....look at the intake port angle.


it should look familiar to 3V guys. its straight vertical. there is ONLY a 45 degree turn into the cylinders. this is F1 stuff. formula one style intake ports. im only saying f1 style.


a 45 degree short turn is about as good as possible. it doesnt suprise me it flows like it does. AND there's more to it.

extremely high flow numbers on (99-05 4v) tumble port is necessary for maximum cylinder filling. the actual volume that fills the cylinders. Al detailed why its that way. the air charge is attemting to overshoot the valves.

well forward to 2010. take the same valve size, deshroud it, and change the port angle from about 80 to only 45 degrees. you get cylinder filling just like 3v. But if

IF it flows 355cfm at max lift you have a high flow AND maximum filling.

If I were to get one that's EXACTLY how I would do it as well, less is more.

should get the 373s, you can get them w/o the track pack

I agree, anyone getting a manual should definitely go for the 3.73s of course. I'd be getting the automatic though which I believe only comes with 3.15s but that won't be too bad at all if the transmission's internal gearing is anything close to GM's 6L80 gearing (4.02 first gear).

definitely the 3.73's, the track pack wheels 255 pirelli tires are an option. that is small still, but at least when i run it for 'bone stock' times it will be respectable.

the widest i can get will find their way onto the car.

I can't wait to drive one when they finally are released

Here is the article scanned. Take note of the head flow, it will suprise everyone. It outflows all LS heads at equal lift.

I have included the head that the engineers mentioned this head outflows for reference.
