500 hp 360 ??

I'd run a solid roller. It would be worth the smal amoutnof extra money for the hp and reliability it wil provide.

I'd also like to see some dyno numbers whether crank or chassis on a dyno not owned and operated by the machinest. I guess i'm not believing such a simple build with stock parts making 225hp+ more than stock. I've had 340 and a 2 440's built. One of them touched the 500hp level....
