Is there anyone who has successfully pushed a 330hp hotrod overhaul of a parallel-valve 540 through a 337 on a certified aircraft? My understanding is that for about the same dollars as a factory engine, you can get 70 extra horsepower. Hard to ignore a 25% horsepower increase. Has anyone installed a Whirlwind propeller on a certified aircraft with a 337? -- Tom Adams said: WHY NOT just stay in Standard category with the use of a Form 337. I can't speak for other type a/c but I have a Pitts S1-T that is still in Standard and I have made a lot of modifications with the 337. Should work with other types of a/c. I admit, you do have to jump through a BUNCH of hoops for the feds but I have found it worthwhile. Attachement 1: part2.html
