370 is pretty much the perfect cubes for that turbo imo, and if you go with anymore cubes you will need to run a forged crank which really is not necessary! I have a brand new 370 if interested, just an fyi.

I would put 4" stroke Crank in Aluminum 5.3 Block that is about 360-365 depends on what bore you go with.
that will give ya low end TQ and an engine size that won't choke your Turbo, good head gasket seal for nice small bore and you get a Super Reliable Combo.
