Has anyone used one of the dual fourbarrel intakes with the ls3 heads.

I think I saw a test somewhere, but I can't remember where. The test showed that it was an impressive performer. Hopefully, somebody with a better memory than mine will chime in. Either way, they look great.

IF my billfold was a big as my desire, I would build a bigger inch LS3 blocked engine with a fairly fat cam profile and around 11.5 comp and slap one of the Holley intakes on it with a dual Fast EZ efi setup. Stuff it all in a car with a pro street vibe with an overdrive 4L80E and reasonable gears in the back. That would be a super low maintenance driver with a some serious street power, but not so radical that you couldn't go to a meet a couple hundred miles away. More bark than bite, but still no push over and just pure turn key drivability .
But to the point, If I remember right ,it was tested in a car craft issue on a pretty strong engine and made great power, but was soft at lower rpms. Not the 1500-7500rpm intake that Holley is claiming, but very strong above 4K.

I NEED A BIGGER BILLFOLD!!!!LOL

so it made more power everywhere. BUT, a true odd ball motor. A 5.3 stroked to a 383 with aftermarket heads and big cam. I'm not sure how any of that would translate to a conventional 5.7 or 6.0

Wrong intake, Pop. The OP is talking about the Holley High Ram for the LS3 heads. It is a modular topped intake that will accept a single front throttle body like the factory plastic intake OR a dual 4 barrel top plate. It is as close to a tunnel ram intake you can get other than a high dollar sheet metal set up.

Sorry, I thought he asked about a dual four barrel intake for LS3 heads.

He did, but the article you posted was a mid rise for the cat heads, which was pretty stellar compared to the Vic Jr they compared it to. 50 ftlbs extra grunt at 3000rpms without any penalty up top is impressive.
