Turbo's "smooth" RV-7

[rv767]

In reference to Doug's comments on the front page about this nice flying 7; It's been a while since the first flight of this plane so I forgot what engine prop combo it has. Could someone who knows elaborate on this plane a little?
Doug...anyone...Bueller?
Thx

Regular 'ol ECi O-360 Titan (slicks and carb) and a Hartzell blended airfoil. I've flown a few RV-6/7/8/9/10s and even a 12 and this particular -7QB is the smoothest for some reason.
