I have a LQ4 that I am putting in my 67' Chevelle with a T6 S88 Turbo.

I am about to order a Edlelbrock Pro Flow XT but I thought I should ask if there are any other options to consider that might be better.

My Throttlebody is a Fast 90mm and I have a 4" cowl hood so I can fit a tall Intake.

Xt fits under the stock hood if you care about that.

I have a 4" cowl.
I will look at the Holley. I want a manifold that won't leak. So I want the tb flange to have the o ring boss not the LS1 style flat flange.

Holley Hi Ram any day. They are great intakes for boost.

I have the Holley Hi Ram, but I can tell you mine just had the flat gasket surface for the TB. That being said, it would be easy to machine a groove for an o ring on the TB mating surface.

I'm just using the paper gasket that comes with the intake, but I've seen a friend put a groove in the TBs to use an o-ring.

I saw my buddies leak meth on the dyno under boost right at that flat TB flange. That's why I want the o ring groove.
BTW the Edelbrock Pro flo XT has the flat flange on their 7139 part # but their 7140 has the oring groove.
