x96535,

You might want to look at how and where the two blower types make power. They are very different to drive and live with.

Your fuel system will need to flow enough to meet that the crankshaft power demands + an additional 50-100hp that it takes to drive the blower at speed. So if your making 650 at the crank you should have enough fuel flow to support 750ish hp.
I prefer to run big hard lines for both the feed and return as it is less restriction on the pump which helps it survive longer.
In the old days we would also drop a couple of heat ranges on the plugs.
