I am building FW190 from scratch from a set of plans that I purchased from AMA. The aiplane is 58" ws and should weigh 5 to 5.5 lbs. The plans call for 35-45 engine. However, the room provided under the cowl looks like will only accomodate a 40. The author stated that he flew it with a "healthy 40" and an 11x6 or 12x4 prop. I dont want to spend all this time building for a 40 size then not have the power to enjoy warbird performance. What do you guys suggest? Will a 40 work? I had a TT gp42 sitting back for this plane but now I am not so sure.

Thanks
Jim
