400 stroker suggestions

What rods and pistons could you use with a 4.15 stroke / 400 Block combo to end up with around 9.0:1 compression ?
I have toyed with this idea for my 79 Dodge motorhome.

What vehicle? I would go with a 4.15 stroke personally. Built many of them, 600HP is very easy however reliability comes from quality machining, quality parts, and quality assembly along with proper break in and tuneup! Check us out: immengines.com
