The last of the fire breathing big block Cougars were built in 1971. They featured the 429 Cobra Jet engine, and carried one of the highest factory horsepower ratings (370!) of any Cougar ever built. Sadly the times were not right and only a handful were built. The '71 Cobra Jet Registry is maintained by Mitch Lewis.

If they were negative numbers?

When the 370HP engine is underrated and/or the 390HP engine is overrated.

Ed Zachary, 370 HP net, and 390HP gross.

That makes sense, gross is always higher than net

The question was a sarcastic comment in reference to the description of the 429 CJ being the highest HP rating in a Cougar.

As the few who answered generally agreed, that 390 is certainly MORE than 370, perhaps the writer was being just a tad too enthusiastic or biased towards that model, stranger yet, is why no one else caught the mistake.

Maybe they were fudging the horsepower ratings down even more dramatically by the time the 429CJ came out, meaning it actually had more real horsepower, regardless of whatever made up numbers Ford was reporting?

What difference does that make? Were not discussing what "might have happened" were discussing the advertised HP.

Whether the 370 was really 410, makes no difference, it was advertised as 370, which is LESS than 390.

By the way, a 427 R code is rated at 425, but in reality it was 465, it was never advertised at that, but if you bought it thru the parts counter, that was the rating.

So does that mean that the 390 HP really is 430 HP ?
