4 bbl intake 273

Any 67 up 318 intake will work on your 273. 340 intakes will also work but have larger ports. I don't like the sp2p intake, because the runners are so small, it stops pulling about 4,500 rpm. It boosts torque on the bottom end, but I like a 273 to pull higher than 4,500. I'd have any 4 barrel intake over a 2 barrel though. Edelbrock carbs are fine but if using a 66 or 67 original 273 intake you have to open up the secondary bores or use an adapter.
