400 stroker suggestions

Yeah that would work. You should read my engine articles since I've built a lot of stuff that is similar. If you have the hood clearance I'd use the Trick Flow intake rather than the RPM Performer but otherwise I don't see any issues with what you've laid out. I'd also add the Hyperspark distributor so you can use the Sniper to control timing. The engine in my Coronet is basically the same thing, just a little bigger since I started with a 426W block.
