I got alittle more info on the intake
No one know the builders name. But it was built for a guy named Gary reavis
For his boosted ls6 after he passed. My buddy got it and was going to use it on his 2011 z71 he was going to turbo but plans changed and he sold the truck.
So now I can either use it or try to sell it or trade it for him
That's all the info I was able to come up with. If anymore is needed I'll do my best
He said on price was $1000. But he is open to any offer. And trade just let me know
