Intake Manifold Recommendation

I drove my 88 D150 for over a year with a stock 96 junkyard 360 Magnum and enjoyed every minute of it. RPM air gap with 1" open spacer and a 770 Holley street avenger it made just over 400tq and 308hp at flywheel. Made driving it anywhere fun. I ended up putting small roller cam and rpm heads on it last winter and it's now hands down my favorite vehicle I own to drive. Little Dodge pickups deserve a 5.9 Magnum.
