Question is, I've built many small blocks up to 450 hp but never built over that and never in a blown application. Are there any tricks for tolerance? Specs? Or any special details I should be watching for when building blown short block? I have a good speed shop here that can do all the machining. Also never done a 400, do I have to worry about steam holes with all these after market pieces?

And no I'm not interested in having my speed shop build it.

Thank guys
You'll have good air/fuel homogenization, but still I'd recommend a reverse dome D-cup dish if possible (example JE Extreme Duty inverted dome p/n 131633-1). Run the quench measurement as you would NA.
