The magnum motors actually started in 91 for the dakotas and in 94 for the ram trucks. The magnum motors will have a dome shape intake. That is the easiest way to tell that it is a magnum. Plus the coil is mounted in the front under the alt.

 

exhaust ports for exhuast manifolds, valves, intakes, EFI (magnum) and TBI and carb (LA).

 

There are performance intake out there, but they cost a pretty penny. Everything else is reasonably priced.

 

It's a roller motor

 

ah im late to the party lol
magnum

 

late as well. 92+ is magnum. pre-91 is LA. 91 is the bastard child though because its still an LA but it has the throttle body/efi of a Magnum
