I'm currently spiceing up my 390 for next summer. Would like to get around 400hp out of the motor. It shouldn't be hard, stock it had 320hp. I believe the combo I will be useing will get me close. Has anyone built any FE's??? I'm going with a Comp 280H cam, Edelbrock Performer intake,MSD ignition, Headers to 2 1/2 duals, Demon 750.
