My van have a 351w-v8-5.8 engine. I want to know what things I can do to improve performance and gas efficency. Everything on that engine is factory. Im considering on buying a Ford 351W V8 RPM AIR-GAP DUAL-QUAD (1500-6500 rpm)carb. It was recommended by a couple of gear heads here in my area. They told me they will improve the gas efficiency. But after that what else could I do?? I was thinking on changing also the intake manifold. I have to change the gaskets anyways, oil is leaking.
I want your guys advise. I love my van big time. I want to give her the best
