four barrel 318

Like these guys say, it depends on the intended use of the car.

I just put an old LD4B on my 318 with a 670 Holley Street Avenger ( a 570 might have been more ideal, but I already had this one). It made a huge difference over the factory 2bbl.

THe LD4B isn't in production anymore, so you have to find them at a swap meet or ebay or whatever, but they're usually cheap, and it matches up well with the 318s ports.

If you're planning on getting serious about the 318, I'd try not to spend a lot of money now, as you're going to want to swap the heads for something better. 318 valves and ports are tiny, even for a smaller motor. I'd look into a magnum head swap or a set of the Iron Ram heads.
