Not sure what this intake is. I think it is a y block but can not find another to confirm. This is the only pic I have. Thanks
I wonder if it was modified to mount a pruned GMC blower case, such as this one posted a few years ago by @Louie .
I agree with others, that's a Y block 3x2 intake someone started cutting up intending to make a blower intake. Looks like it could still be used for that purpose but someone will have to take over the modifications where the last person left off, and it's got a ways to go I'd say.
