Yes, I did do a 505 engine with the 292 HR cam but if you take a close look at the article you'll see that the compression ratio was more than 12:1 so that helped a bunch.

That cam will make nice power in your setup but I'm not so sure you'll be very happy cruising down the highway. A freeway flyer with 3.23 gears needs to have the engine set up so it is working really efficiently in the lower RPM range. Otherwise you'll just suck the gas tank dry.
