I'm completely bumbed (sp?) out. John caught me overstating the out put of my engine.
OK OK Now the truth, so help me God. It actually only developed 471.8 HP at 6200 rpm. I rounded it up to 472, do I get 40 lashes with a wet noodle? On that pull, the torque was 441.2 lbs at 4700 rpm but on another pull it was 448.1 lbs at 4800 rpm. Peak HP on that pull was waaaaay down to only 468.1
.
Believe it or not, the Ford SVO "N" heads were just cleaned up and polished, not really ported at all. Since this engine is intended for 99.99% use on the street, I chose a dual plane Performer RPM intake so the HP numbers could easily have been quite a bit higher with the heads ported and a single plane intake. The dyno doesn't lie.
Oh by the way there is an E M Cobra near here that has a 500? cu. in. Dove FE in it. This guy has spent a fortune on the engine and has rarely done more than a couple of hundred miles without a major problem. The engine has been pulled out of the car many, many times. This is a street machine, not a race car, I doubt that it would last very long on the track. I believe that he now has something like $30K US in the engine.
