As Sparky highlighted the cowl of the Bonanza and the T-34 are practically identical. The cowl tapers off to the front so the best type of engine would be a 4-cylinder engine. I believe Mike Barbee's engine on his T-34 plane has, I believe, a 222cc four cylinder engine. Most four cylinder type of engines drop fit inside the cowl. However, there is always the dreaded cooling and baffling problem. I believe it is a must on such planes.

Here are a few shots of the cowl I made. My intention is to have open cowl hoods and that is why you see the large openings on the cowls. Meanwhile I am also enclosing a photo of hood placed against the. The hood still needs trimming and fitting out. I could make it separate or a one-piece thing

Are you sure that Ziroli is selling the T-34 canopies? I did make a search but nothing resulted. I did make my own canopy mold but as yet I have not extracted any yet.
