Which single plane intake?

When i ran my 416 on the dyno i found a old holley strip dommenator worked the best. Belive it or not the victor was to big for the 416. sure it made 20 extra horses at 6700 but torque was down 40lbs across the rpm range. I also ran an x-celerator and it was very close to the holley. I tried a super sucker 1 1nch tapered spacer on all manifolds and it helped alot. Stay away from the victor if its to big for a roller cammed and ported 416 its deffently to big for a 360.
