So this is what the edelbrock site says

Chrysler Magnum 5.2L & 5.9L V8
RPM AIR-GAP MAGNUM (1500-6500 rpm)
Designed for 1992 & later 5.2L (318 c.i.d.) and 1993 & later 5.9L (360 c.i.d.) Chrysler Magnum V8s, the RPM Air-Gap manifold allows the use of a carburetor on these originally fuel-injected engines for use in early muscle cars and street rods. This dual-plane manifold design incorporates the same race-winning Air-Gap technology that's been used on our Victor Series competition intakes for years for outstanding performance in the 1500 to 6500 rpm range. The Air-Gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. Match with Performer RPM cylinder heads for maximum performance.

So does this mean they dont work on our trucks or what. it says it for a 360 5.9l v8

 

it means it will work if you want to run a carb.

 

it will also work if you wanna get crazy and drill holes and weld in injector bungs
