I was wondering what this plate does and what's under it? I'm not sure if I should just take it off and call it a day? I'd like to make sure it's not leaking anything I sprayed in there and going back into the engine?
Thank you for any experience...

What's under there now is a bunch of caked & flakey carbon from baked oil. There is good chance that some of those flakes fall out into oil & lifters. It was originally to prevent oil splash from heating manifold. I was planning to reuse manifold by taking off plate and cleaning it. Instead I found an aluminum intake.
 
Heat shield for the carb. You can remove the 2 knurled (sp?) fasteners, and clean it out. The 2 fasteners just hammer back in. I start with an old putty knife and hammer to remove them.
 
The two pins that hold it on are spiraled splined, use a metal scraper and hammer to start them loose then vise grips onward ho to remove them, then clean out the crap.
 
I never gave it much thought, but I figure it's a heat shield for the oil! The exhaust crossover is suppose to heat the carb for drivability, emissions, etc. Any oil that works its way above the shield gets cooked. But at least it gets trapped. If the shield wasn't there, oil splashed onto the underside of the intake at the exhaust crossover would get cooked on a regular basis and get recirculated into the engine.
 
I blew all the debris out of mine with a Barrett .50 cal and then I bolted on a supercharger intake with an 8-71.

Then I woke up. :-(
 
This is by far is the cruddyest motor I've ever encountered... I'll knock it off and clean it out... Me too I normally get an aluminum manifold and put a four-barrel on it but this is a different project... The two barrel gets a rebuild and goes back on...
Thank you men..:thumbsup:..
 
You could thread the holes and use a machine screw there instead of the fluted pins. Use red or green lock tite on them and they will never come out.
I remember the old 5.0 fords were terrible about building sludge under those plates. I have seen it where its literally hard as concrete.
 
I leave it on get a oxy/acetylene torch start the carbon on fire then use compressed air and blow it out till there’s no smoke or crud , never tried to take it off ?
 
I just use a flat file with teeth on the thin edge and file two flats on those rivets, then you can put a Minnesota micrometer(adjustable wrench) on them and twist em a little bit and they'll just back right out.
 
I remember cleaning out that passage and the holes in the heads that were plugged with carbon on my '69 Coronet 318.
I used a chisel to turn the screws out, it was pretty easy.
After the heat crossover was cleaned out, the choke and carb worked way better when the engine was cold, the stumble disappeared entirely which made the car much better to drive especially when it was -30 below F.
You'll be happy that you did.........

I would love to go around and answer just the titles of the threads all day long...
I think the last one was Trail Beast asking why is it so hard LOL.. of course my advice was if it's lasted more than 4 hours to seek medical medical attention... That one still gives me a chuckle when I think about it..

If it lasts more then four hours I'd seeks professional help all right...but I doubt I'd call a doctor

If you decide to sandblast that area, you must remove it and clean out the remnants....ask me how I know!!! :)
