Thinking out loud..

He already probably has 1000 to the wheels with his 500" turbo Big Block right now!

Yes you are correct... Waive of the future is new school. Those heads flow a
almost 400cfm out of the box no?

I wasn't sure if he meant 1500 fwhp or rwhp. If he's hunting 1500rwhp that's around 2k at the flywheel. I don't think anyone has gone that far with a gen III block.

You're right about the heads though. 09+ 5.7 heads are cheap and flow around 400cfm.
