509 rotating assembly

[Stovebolter]

Any track oriented real world thoughts on the 509 BBC? Its the next step with relation to the 427.....bore to stroke ratio the same. Piston speed same. I'm thinking about staying with the Rat pack and adding the ZF 6 speed. I would probably use a 502 block and a lightweight balanced rotating assembly. Eventually would like to try out the latest stack injection as well.

I realize the big block will make the front end a bit heavy. But what does it feel like compared to a fast rev small block? I would liken it to that of a heavy 302 with a lot more torque?
