91 V8 Questions

Magnums had better flow but inferior/cheaper (to make) valvetrain design. Id go Mag if I had to make a flow choice in heads, but that also limits your legacy LA intake choices. Probably not noticeable in a mild build. TB injection was a transition between carb and MPI, not the greatest either as it was still a wet intake with all their carb flow pitfalls. Dry MPI intakes can look like a 904 valve body and still flow well as air is much lighter than air/fuel, and there is nothing to fall out of suspension and puddle.
