Josh how do you think the Pro Flo is doing? I was kind of skeptic about its somewhat small plenum size, but I am coming around to it.

We started on my motor mounts today and I was measuring stuff. I have about 1" of clearance from the top of the intake to the windshield. I'm not worried about cracking it. I don't even think spacing the k-member down will be necessary.

Oh and also the cathedral port versions are being delayed because of a casting defect. No ETA was given.

It's 12" tall at it's highest point with the lid on it. It can be done.

yeah stangkillrs car is the main reason I wanted the thing after I saw how badass it looked, much less the gains. But dropping K members down, and switching to solid mounts, is certainly not going to keep my driveability where i like it. that pro flow is starting to look pretty good though. I think they come like that. no need to powder coat. looks sweet to me, yeah the plenum is a bit smaller, but its still gotta be better than my ls6. i am going to just give it some time and let all these people trial and error it though, before i make my final decision. its too early to tell. I think it may be possible, but I am not an R&D kinda guy when it comes to my own car.

I love it! Guys need to remember that bigger isnt always better on plenum/runner size. I cant comment specifically on the Holley, but im really impressed with my pro-flo XT. it has great throttle response off-boost, looks great, and obviosly performs well. 1020 rwhp at 17psi tells me theres not a whole lot of restriction in the system considering I have a cyl head with a 215cc runner, and a baby cam with 228/230 duration!

Man,
Idk if its the same with stock kmember clearance? Im thinking would prolly rather not cut up too much cowl sheetmetal or hood fiberglass on my or ws6 hood. But i really want to use this intake over my fast 90/90.
Just for looks really, but i would bet it outflows a fast by a good bit.

Just checked with my sources at Holley. Looks like another few weeks at the very least on the cathedral port!

I've been having great luck with the Pro Flo!

yeah, they both def flow well, but my main concern is the wow factor when I pop the hood. I am actually trying to get some trophies for my dressup etc...otherwise id chop it to hell and back.

It comes with bolts and a spacer to bolt it to the side bracket on the intake.

I'm not sure if you can or can't run other rails. But since it was an awesome deal to buy the intake with the rails, I went ahead and bought the whole package. Total shipped was like $589? That's a hell of a deal considering fuel rails like these regularly go for $200 alone. I like them. These are quality. Edelbrock fuel rails are junk.

I do plan on powdercoating it black with red letters on the Holley logo. Should look bauce with all the other murdered-outness in the engine bay.
