I'm interested in knowing why your "stock" 426 Hemi made more power than ANY of these 500 cubic inch, highly modified hemis that competed in "Mopar Muscle's" 2005 Hemi challenge.
If you read his previous posts, they had one week to build 3 motors. They used parts they had on hand- not factory replacement parts. So ehile the Hemi retained "stock" type cast iron heads & a flat-tappet cam, what they had in stock @ a race engine shop are probably not stock spec. Same goes for the other two engines. He even admits that the hemi was massaged a bit due to the parts selection they had on hand. On another note, they were told to do a build-up similar to what would have come out of the Yenko shop, Mr. Norm's shop, and whatever Ford performance shop of the era (Shelby?) I doubt their engines were anything close to stock...
Don't read too into stuff. Judging on your registration date, you're probably a chevy or ford lubber looking for a fight. And, as was mentioned, the tunnel port ford was never a factory option- as was the Street & Race Hemi, and the Chevy L88. So, Stop being jealous & enjoy the entertainment
