Fan shroud compatibility

Will an original (german)1200cc fan shroud work with a built up dual port motor? I found one without freshair holes and would like to use it for my engine build.

There's good aftermarket fan shrouds without air duct holes in them. I cut and welded my original 1600 dual port fan shroud, but the welding warped the metal a bit, so the fan would rub slightly. I had to tweak it to fix that. Not a big deal, but it was so much easier to just buy one pre-made, that fit the oil cooler location of the dual port case. Mine's a "36hp" style fan shroud, which leaves lots of room to adjust the dual carbs.

Aftermarket shrouds suck in my opinion....no doubt

It will fit if it's from a `61/`62 non-fresh 40HP (a true 36HP shroud won't fit on a 1600 case without butchery) but it's designed for the old oil cooler setup which was borderline for stock engines and inadequate for hotrods. Even if you use a remote cooler, this kind of fan housing lacks the internal vanes that distribute the air to the LH head - with no cooler inside, they'll overcool the base of the LH cylinders and undercool everywhere else. You can do better.

Massive Type IV,
I wouldn't argue that aftermarket cylinder tin sucks...It always leaves huge gaps that sort of defeats its purpose in the first place. As far as the doghouse, though, if you want the "early look" on a later engine, I can't think of any better way than to go than aftermarket. I know a guy who modified an early shroud to fit a 1600 dual port, but it was major surgery and maybe not worth the effort (he thinks so...for him, welding is theraputic). Is there another way? I wouldn't be surprised if I've been missing something.

The fanshroud from a 73 Thing is a factory solution. It has no fresh air ducts (used gas heater) and is made for late DP engines.
Good luck. Bob Ingman
