Just picked up an M90 for my ls1 z28.

What are the dimensions for this outlet flange? Like how tall is it?

Can I build my own flange that isn't as tall? Will this effect performance?


I am just trying to mock up where I want to place the supercharger, with slim hopes of using the stock hood.

I am referring to this piece below the supercharger



With the 3.8 on it




If anyone has one for sale I am interested.

 

You really should look for a m112, I believe pocket maxed out a M90 on a 5.3l, if I recall he had a few lbs of boost till about 4000rpm and it then became a restriction.
