I have a 86 Monte Carlo LS and I have installed a 5.7 Vortec out of a 96 Chevrolet pickup and I am having a problem with the power steering pulley too close to the steering gear box, and AC Compressor clearance from hood. I do not want to install a cowl hood. Will I have to replace Exhaust manifold? If so, what headers will I need? I have already installed the electric fuel pump and I plan re-work the wire harness. Also, is there a bracket kit to help reposition the throttle cable?
