Some time ago we did a 428 FE Ford Engine for a customer. The goal was to appear stock on the outside and have some hidden hardware underneath. We also wanted to do this with mostly catalog parts and original pieces. The result was 500 HP at 5000 rpm on 93 octane gas from Citgo. The engine was put into a frame off restoration 63 Galaxie 500 XL. The car was finshed this summer and the owner is thrilled! I drove this car recently and it was a treat. You can fry the tires at almost any speed and the car don't look to bad either.
