The "where" to me of the horsepower is of interest. For example in todays top fuel cars they say they are ratedat 8,000 hp. However as they go down the track a bit, that hp is boosted to 10,000. So I wonder what part of the power band did they rate the 435 horse.
I am not saying the article is not truthful at all. I enjoy the engineering that goes behind those things, especially what they did in 55' vs crate motors today that approach 1000hp. That kind of engineering made the NHRA what it is today really.
I am sure the bottom end may have held up, wonder what the connecting rods looked like. Burn a piston mabey? Wonder what the total cost was in todays dollars
Cool stuff.
