Being in the engine building business has to be a trip. Like in any other industry, your main job is to serve the customer and give the guy or the girl exactly what they are looking for, whether you necessarily agree with it or not. When you go to a restaurant and you ask to hold the sauce, the chef does not come out and berate you. When you hire a house painter, that guy is not in charge of picking the color of your home, he’s in charge of applying it, right? We bring these scenarios up because the engine build you are going to see below is likely one that made the builder himself squirm a little because in some ways it is just wrong but in many more it is right as rain.
This is an outwardly stock appearing 427 FE top oiler engine. The thing actually displaces 498ci now and in spite of that wears a factory unaltered intake manifold and even more wild, factory unaltered heads. The owner of the engine wanted the ability to someday put it all back to completely stock if he needed to so the heads were not so much as even ported!
As one would imagine, there’s power left on the table here because of this but there’s also plenty of power being made to propel whatever this engine is powering down the road. The mill makes more than 470hp and it makes 500+ lb/ft of torque until well over 4,000 RPM. There’s tire frying twist available whenever the driver wants to stand on it.
We dig this engine because it is “wrong” in the traditional sense. Yes, head work or even just plopping on a set of aluminum, modern designed FE heads would free up scads of power but that is not what the customer wanted. Agree or disagree, this engine has to be fun to operate!
