I got a stock vortex 350 I done the throttle blade mod cold air intake and took the resonater off how much horse did it gain
adding the K&N Filter sticker and the flowmaster sticker yields about 50 net horsepower to the wheels. But realistically i'd say about 5-10 HP? Why not Dyno the vehicle and see for yourself?

Your truck is not TBI as you stated… It is a sequential fuel injection system.
It is rated at 255Hp and 330Tq
about 250-275 hp.
255 hp and 330 ft lbs torque. IIRC all 350 vortecs from 96 to 00 had the same HP
