360 windage tray

Hey Rumblefish -
I agree with you, but you missed the decimal point placement in your math. The difference in stroke is 0.270" total; 0.270"/2 = 0.135" - just over 1/8". But I agree, I've never seen a windage tray prove to rob power. I'd just make sure there's sufficient clearance by spinning the engine over on an engine stand with the oil pan off and trim the tray if necessary.
