What are the bolt dimensions for a 6.7? Are they all the same?

Do you mean the manifold? If so the bolts are M10x1.5 thread, the same as the rest of the ISB family.

I mean the actual bolt pattern. Like 2.75x3.25. Curious where it falls in the family of t3, t4. I understand it is neither, but what are the dimensions?

Great, so we are sure they are a t4i?

It is showing the t4 is 1.75 between the holes?

I was thinking the t4 was 2.75x3.25 It looks like the dimensions might be a little off. Can anyone clarify?

Thanks, do you see what I mean about the dimensions being unclear?

Its actually not t4i.. It is a WGMT flange. I posted a drawing on here somewhere with the dimensions, give me a little while to track it down.

Dan I am watching and will have to measure the 6.7 at work.

Here is a link to the thread that has a drawing of one of the plates I made to mount my HE351VE on my 12 valve, shows the WGMT flange dimensions:

The 6.7 flange (351ve) is as close to a T4i as T3 is to T4.

So 3.58 x 2.13 centers on the bolts?

Yes. I made mine to the dimensions on that drawing and it fits very well.

Here is the drawing:

Neither he351ve that i have has a T4i flange. Unless they changed something they are the wgmt flange.

I do have a he551v that uses the T4i.

Yea I guess I was referring to it wrong. It isnt the t4i. However it is larger in one dimension, and smaller in the other.


Thanks!
