When I finished my first -4 in 1984 I asked the old mechanic at our airport, who also happened to be a WW2 P-47 pilot -how should I break the engine in. He said and I quote-fly it like you stole it....

RV-4 weight

Good posts about -4 weights and I agree with Scott. Any weight under 935 is about right for a 320 and wood prop. My first -4 serial number 706 was 916 lbs with an 0-320A2B and a pacesetter 200 prop....
