Would anyone happen to have a picture or knowledge on the lower intake manifold for a 6thgen? If i'm correct, the port holes should be different sizes than a 5.5gen!
By the way, sorry about the misspelling in the heading! Just noticed it.

 

It's the same.


Title fixed.


Edit: A worthwhile LIM would be the Z33 unit with accompanying upper. It's better than the FWD manifold for 3 1/2 reasons.

 

Ahhhh, so only the z LIM has equally matched ports!! Got it!!

 

The thing is, the reason the FWD LIM has the uneven ports is because the air going to the rear bank has to make such a sharp turn. This would cause a pressure drop on its own so those port opening are made smaller to try to keep velocity up around the bend. It's a compromise caused by a compromise. The overall port area when you get farther down is the same as the other 3 though. The Z LIM just has more area all the way around.

 

I sure wish you would have a class on air velocity, heads and intake volume

I know a few people that could use it, matter of fact a class on how a engine works

 

Where do I sign up?
