I've installed and tuned a bunch of 32/36's on BMW 2 liters. They are really well matched to that engine, a good blend of economy and power. I feel they are probably on the small side for a 225, although the 225 and the BMW make about the same horsepower. You can jet them up if needed.
The Jeep guys seem to like them for their 258's. You might jump on a Jeep forum and see if those guys are doing anything special to get these carbs to run right on their motors.
I've got a few 32/36's laying around from my BMW days, and also a 38/38. I may try running one on my slant... But I've also got the correct Carter for the Super 6, so why re-invent the wheel?
