I have a 360 A block with a crane 272-2 cam in it the motor has 10:1 static compression with match ported iron heads to a edelbrock rpm air gap manifold.On top i run a 650 holley street hp. The vehicle goes well but i have a comp 280 H sitting at home was just wondering if there would be much of a change if i went up to the 280h.. cheers daniel
