You should see any where from 8-13rwhp gains and 10-15rwtq gains.The 5.3s are strong and put out better rwhp numbers than our vortec 350s,but the torque is preety closr to the same.But we wont catch them on rwhp.Ive vortec350s put out a little more torque than the 5.3s on the dyno but the 5.3s had more rwhp.
