Engine is a 366 w/Holley carb. Just below the carb there is a void into exhaust crossover of the intake manifold. The truck has 80050 miles; used to be a Vol. Fire Co tanker. Just got the engine to run and exhaust blows out the intake crossover. Hole is about 1/4" x 3/8". Repair options I have considered are furnace cement and welding. Any advice? I have a wire feed and stick welder; I have welded alot of mild steel; but not much experience with cast and no successful experience with cast!!

Is that actually part of the manifold?
Or is it an aluminum spacer under the carb? If it's a spacer, that can easily be replaced.

Can you post a picture? Ford Did not build a 366 engine.GM built the 366. It is a 330-361-or a 391.Some of these trucks had an adapter plate under the carb with heater hoses connected to circulate coolant through the adapter. I think you need to take a closer look and forget about the welder for now.

Ford didn't make a 366, most Ford fire trucks came with 361 or 391 engines, 391 would have a four barrel carb.
The hole your describing sounds like an exhaust port for a EGR equipped engine that used a special spacer between the manifold and carb.
First EGR engine's I remember was in 73 or 74, not sure when they put EGR on HD engines but the 75 F-700 we had didn't have EGR. Pictures and numbers from the manifold would help.
The VIN carries an engine option "E"; which I can not find a reference to. I had a Ford trained tech emphatically say it is a
366 when he brought the carb kit that was incorrect and returned with one that fit. Another said the 366 was an industrial
engine and the single speed differential would limit the truck in top speed. It has a governor, hand throttle, hand choke, and
tachometer; all pretty unique for 1969. Sure wish the siren had been left on.

All Ford MD trucks in that time period came with hand chokes and governors, all fire trucks came with hand throttles and tachs. A 71 LT800 I drove had every thing you listed as standard equipment with the 391 engine.
Looking at the pic it's not a EGR manifold and could be a blow out in the casting.
Two barrel carb so it's not a 391, Holley carb and governor makes it a HD engine, MD engines had Autolite carbs and different governors.
If it doesn't look like the 361 on your stand show a pic of the entire engine. Normally there was a big decal on the air cleaner that id'ed the engine
Understand there's a lot of difference in MD and HD engines of the same size.
Ford NEVER made a 366 engine for trucks during that time.
From around 64 till 78 or 79 they used 330, 331, 361, 389, 391, 401, 477, 534.
Late 70's thru 80's and 90's they used 370 and 429 engines.

drill and tap put in short cap screw. As you wished siren was left on tap to pipe thread and install exhaust whistle
rnie(quoted from post at 18:26:33 02/06/17) I tried to post a picture and failed. Not the first or last. It is a casting flaw in the CI manifold; it has a heat shield under the carb; no aluminum plate.
Letter code " E " is for a 361, 1968 - 1970 according to my old Motor's Manual. You can check the distributor # 361 used # C8TF-12127A
If it has a different #, let me know and I can tell you what engine used that distributor..
