Remember the days when a 65mm throttle body was the big upgrade for a 5.0? Some of you are probably too young, but it's true-a single 65 was big back in the day. These days it seems you can't get big enough. This is the latest power combo from VMP, a dual 72mm throttle body and high-flow inlet elbow (PN 72ELBOWBLK; $799; $39 upgrade for polished TB; $75 upgrade for polished elbow; $100 to add motor and TPS). If you are only shooting for 650 or lower, you can go with the same package with the VMP dual 67mm throttle body (PN 67ELBOWBLK; $769).
