There's a guy on tthis forum that has that setup. I put one on a SB Ford for a guy with a Cobra, and It flowed a ton. he had to jet it way down to make it work, but it fit under the hood. Not sure about the clearance on a vette, looks too tall...

ram82fire has one.

The only disadvantage I can think of is tuning...oh and cost

You cant use tall valve covers with the crossram, thats why I went with the downdraft version.

With these setups it's getting expensive and I believe the runners on the moon intake were pretty small (not out of experience) I went with the DC&O EFI crossram setup (not completed !). With all the necessary hardware, it gets a pretty expensive setup. An Australian friend I got to know on this forum has got the DC&O working on his C4. Even with a stock engine it seems to really be worth it according to him.

Oh yeah, you cannot use a HEI with them.

I hope that means ext coil, I assume that would be possible. I myself used a electronic controlled dizzy with external coil. It was the only thing that would fit and even that one is really close

It looks pretty cool. Clearance-wise it'll fit in any Vette....as long as you don't have a phobia of using a cutoff wheel to cut a nice hole in your hood.

Mine fits without cutting the hood, not even by far a clearance problem. I don't think the moon has a problem either.

It even fits under an 82 hood with the entire air box in place.

My brother has a similar setup under his hood and he lowered the entire body and birdcage onto the frame (no body mounts) and it still fits (L88 hood).
