Marine sbc efi intake?

[70TWO NOVA]

So I've been scouring the interweb for quite a while for a dual plane MPFI intake for a gen 1 small block chevy (seems like they don't exist for some reason) I plan on converting my carbed 355 in the Nova to a port fuel injection setup using microsquirt to run it. The car s primarily street driven and occasionally autocrossed so I would like to maintain good idle and plenty of low end torque the dual plane intakes provide. I finally came across the intakes made by Mercury Marine called the Mercruiser quicksilver Part #: 8M0061387 (see link below) I'm interested to see if anyone has used these in auto applications and where I may be able to find a used one. I know I can get a new one for about $400 but I prefer to buy used. Any info is greatly appreciated
