This is a type of set up I've never seen before. They've taken an 8 port Kinsler injection set up and mounted it to what seems to be some type of an adaptor that gets bolted to a tunnel port manifold for a SOHC motor. Has anybody ever seen this type set up; fuel injection sitting on a regular manifold instead of a blower. I'm also curious about the non stock holes drilled into the intake runners, for nitrous maybe from a prior installation.
These are photos of a SOHC blower manifold
