Another 400 question

[Don Rudolph]

My 400 Super has an 800 motor which means the muffler exits through a hole in the hood that was cut in with a chisel. I am not kidding. My question is can I go to a salvage yard and get a 400 intake and exhaust manifold setup so the muffler is outside the hood? Or, are 800 head ports larger than a 400 manifold? Thanks, Don

Don, I have a spare exhaust,and intake manifold.I could take some measurements ,and we could compare measurements.CM

 

[brutus49DC]

the same gasket set is listed for both models so there must not be much difference

Don, I have a spare hood if your interested. In Northeast Wisconsin.

Interesting, I have exactly the opposite problem with my 611B: a very pretty 3" hole with no apparent purpose, roughly above the distributor. I put a Caplug in it.

The manifold mountings are the same for the 400 diesels and the 700,800,730,830 diesels. Also the manifolds will fit the gasoline heads. We have a 400 COM that used to be an 800. It has all the Super 400 stuff plus the COM.

Wonder if a 800 hood would fit on it?

Probably was replaced at some point with one from a 300b diesel. The upright exhaust came through the hood on the right side.

Tom , You are thinkin too Fast LOL ,. ,you are probably realizing now , the 800 hood is squared more than the 400 hood

 

[Case Nutty 1660]

Ahhh You are So Correct I was just thinking how he could do it easier than changing the manifolds Duh sorry

800 hood is longer. There is a difference in the front tub between the 400 and an 700 ect. The hoods will not interchange without changing the tub. Actually you can put a spacer between the tub and the engine block, about 3/4 inch

Hello Ken,

I might be interested in that hood. Could you send me an email? Thanks, Don
