Is anyone using the GMPP intake for the LS7 heads?
Is anyone using the GMPP intake for the LS7 heads? I'm building a 450 stroker and was originally going to run the WCCH Stage 3 L92 heads, but I think I will be going with either the Brodix BR7 or PRC LS7 285cc heads. I am now looking into intakes and because of my budget, I was thinking the GMPP since I already have a Accel 4150 1350cfm TB.
I know the GMPP is not the FAST LSXR or the Cary's 2pc intake, but is it worth getting, or should I get a OEM LS7 intake?
If there are any other intakes to chose from, that don't cost a billion dollars, please let me know. Thanks!

I am running the prc 285cc head and the ls7 intake on a 454. You can't port the ls7 intake enough to port match the heads you would have to port into the oring groove. If you have the clearance I would do the gmpp even over the fast. It will make more power than the fast and ls7. Just my 2 cents.

I'm running the GMPP intake as well. Ported to match my LS7 heads. Only draw back on this intake I see is cutting the cowl and your hood. I am also running an Aarons intake elbow. Heres a few pics for you:
I also had an issue getting the fuel rails to seat correctly. What I ended up doing is custom making fuel rail brackets out aluminum. Its pretty ugly, but they work. And my buddy made me a bracket to hold the throttle cable as well. I'll see if I have a pic of them for you.

I would be using a Accell 4150 TB. I don't care about cutting the cowl and I have a VFN 4" ram air cowl hood so I doubt I'll have issues with that.
I'm just wondering how the performance is with this intake. It will be sitting on top of a 450 stroker so I want to make sure it will be the best "out of the box option" for the LS7. I just know they suck for the LS3 heads, but since there's not too much of a choice for the LS7....
BTW, why did you go with the elbow over a 4150?

Mix up at the builders when I ordered a 90mm, so they bought me the 92. I also have to mention my engine builder ported my GMPP to match the ported LS7 heads. He once told me he didnt like the way a vic Jr flowed, with the restrictive elbow. Hope that helps out a little. I'm trying to find my build sheet to see how much they charged me for the GMMP. **** like that makes me not even want to use a company! What if you bought the rail and the damn bracket broke... I guess they would make you buy another ******* kit...!? **** like that pisses me off!
But I tried my best sales skills to get them to send me the brackets, and searched everywhere with no luck. I guess I am just too honest. Never thought of telling them I broke a bracket, hahaha. Lucky for me I have a friend that is very very skills in the automotive crafts He made that bracket for my throttle cable for me. He's a lifesaver they are OEM castings, 8452. They were a bit pricey back in 2007 when I was having this motor built. Chris Frank at RayMac Racing Engines, Ft Worth TX built my motor. However he has his own company now. www.frankensteinracingheads.com

Yeah with A/M that's starting to hit the scene, the OEM need to come down BIG TIME! You can get a set of bare Brodix BR7 for $500 each and RHS is coming out with their Pro Elite for around $500 as well. A fully dressed and CNC Broxid is $1500, so yeah... the OEM LS7 need to drop in price!
I'm just going to do the Brodix BR7 heads. They are $1500 dressed and that is with a factory CNC, which ain't all the great, but till I get the cheese to have Rich work them, it will do. I just wish there were more optimal intakes for us to chose from, without having to rape out budget. 
And just to mention it, Rich's Stg 3 Brodix BR7 heads are only $500 more than the PRC LS7 heads, but then again, the PRCs are 8 bolt, but since I'm N/A and my block is not provisioned for 6, I not worried about it.

I am not too sure how much I paid for my intake, but on Scroggins site its not too bad:
