LA to Magnum HP boost.

Did the roller cam TBI engines have "worse cams" than the Magnums? Don't know. I'm sure the intake was better overall.

Frankly there are NOT huge power gains just because of TBI vs multiport. It was cumulative, and likely improved software/ hardware in the years that progresses

I also don't see any big gains in the rockers or the belt drive. Ports? Yeh. And don't negate the torque gain. Any boost anywhere in the curve is a plus
