LA to Magnum HP boost.

Whoa, check this 91 Dakota 318 to 92 Magnum 5.2 HP jump:

"1992 Dakota
Both V6 and V8 engines gained a whopping power boost. Horsepower jumped from 125 to 180 on the V6 and 165 (LA) to 230 (Magnum) on the V8."

Man, that's a 40% power increase! In part due to Magnum heads superior closed chamber double quench heads, cam, kegger long runner intake, and MPFI over the lame TBI of the injected LA.

You go from a pitiful 170 cfm intake port to a 210 cfm intake port and better exhaust port. plus a 1.5 to 1.6 rocker ratio.
