Here is the link to the latest Chevy High magazine with our 500 ci in it. You can check out some pictures in it but we are working on our new website and it will have better pics of the machining process on the website. It should be up in about 1.5 to 2 weeks.

Actually a high duty cycle engine like a top speed type engine (plane, offshore power boat etc.) would always be much better served with a larger lower rpm engine every time and that is in fact the way the industry builds them. Small stroke high rpm engines are inherently unreliable and only seen in rules oriented class racing. The only reason you see small engines in any racing is the rules to keep the power down. They are governed by insurance regulations to cover their events like every other business or sport.
Believe me it would be MUCH cooler to see 600+ inch 1300+ hp NASCAR racing but most drivers would be dead within the year. The ratings would be unbelievable though!

Thanks for the kickass info in the past couple posts. I think most here are always talking about 1/4 mile drag racing. I will never ever do that. So rpm's for top speed type runs are important to me.
So I guess an engine that only spins 6300 rpm, but makes a ton of power/torque just isn't the right engine for me.
I PM'ed you a question about a 454ci, I have to know something.

It all depends on the dyno graph. In their article, they said it made 717 @ 6500 rpm's. Mine made 508 @6600 RPM's. Also, what was the torque with the 530 RWHP? If it was 750 then there is no comparison! But consider my bottom end is still the stock 364. More displacement will spin less rpm's and still make tons or HP and TQ.
If you seen the car and spoke to the people who built it then there you go, I'm only going by the article I posted. Guess you really shouldn't believe everything you read.

We recently completed a Warhawk 496 that is scheduled to be installed April 1, 2009. Ill be sure to keep everyone updated on final #s and the entire build process
Here is a sneak peak with the new ARH 1 7/8 x 2 Longtubes bolted up.

Will this be an N/A engine or is it slated to see BOOST?
What are your projected HP #'s?
Nobody has mentioned piston speed with these long 4.5" strokes. Builders like Katech told me long ago they won't build anything with longer than a 4" stroke because of piston speed. They may have said 4.1", but I'm pretty sure from memory they said 4".
Is that a problem with a longer 4.5" stroke?

I don't understand why you can't rev these 500's to 7k? If Sonny Leonord's 802ci. motor makes max hp at 7100, why is it such a big deal with these? Especially if it's an ERL block. Oh by the way, that 802 made 1417hp at 7100 rpm, N/A, on 89 octane!!!!!!!!!!!!!! I WANT ONE 
. They also have an 898ci. monster that made a hair over 2000hp the same way!!! I WANT ONE OF THOSE TOO
