ring and pinion ratio suggestion

-- If You really want compromise, I would say the 3.31's, that's about 2825 RPM@65 MPH. Not "screaming", but it's up there a bit, w/it You'll get an 8% improvement over 3.07's
in Your takeoff gear. Your 'teener will appreciate that! --
-- I agree -- 3.73s would be close to 3,200 RPMs at 65 MPH, due to rather small tires. -
