Hi all!
I'm looking at an RV-4 (to buy) which sports an O-320 E2A. The owner says the engine was converted, by a previous owner, to a Constant Speed prop engine by, he believes, replacing the crank with a "hollow crank".
Also the 7:1 compression ratio was boosted to 8.5 via higher compression pistons.
Does anyone know of serious problems that occur when one converts an E2A in this way?
thanks!
