naturally aspirated, non stroker, 60 over, 360, 500hp, is it possible?

Here's the thread on it. Major secrets are light pistons with custom ring pack, hydraulic roller, K1 H-beams, and a really good builder. http://www.forabodiesonly.com/mopar/showthread.php?t=241854 Here's a video of it in the car with a street roll of ~5-70 with a 3.23 ring in the back. https://www.youtube.com/watch?v=BxQkNYRDAD8 I'd say it cruises rich and I'm getting 13+ mpg city without trying. Idles nicely at 900.

That's cool I saw that video yesterday didn't realize it was your car. What size tires you have in the back, and many RPMs you turning at highway speeds? I have a 2.94 gearset for my Duster with 28" tires and I'm thinking of picking up some cheap 3.23 gears as it's a little too tall for my driving. Sounds awesome btw.

To the OP back in the 1970s Chrysler developed the W2 racing heads for NASCAR which made over 1.5 hp/c.i. (600 HP) in a 360 so just keeping that in mind 500 is definitely doable with modern aftermarket 'street' heads. Just make sure you got the right gearing + trans setup.
