I have one that's going on a mild SB. spread bore/318 ports/divided (2 plane) plenum, didn't know it came in a single plane. I have a streetmaster single plane alum intake on a 318 right now.
How did it do? I'm getting ready to try a 66-67 273 four barrel intake on some 302 heads on a 69 318-3 block with a Summit cam with 455 lift.
