Thanks. But, the M/400 uses what is referred to as the "turkey pan" that covers the vee of the engine so there is no oil nor hot gasses that hit the intake. I've attached a picture so it is easier to understand, but there is no contact between the intake and the turkey pan, much less the hot oil.
I know, but depending on your manifold choice you don't have to use it. Shoot IDK if you can use one, with the 400 deck height and Cleveland style heads if you can even get one that will fit the intake ports. From what little I've read I think your stuck using more "mormal" intake gaskets and RTV on the end seals. Nor for you do I think that heat source would matter much with the aluminum heads and I assume aluminum manifold.
Gary,
You can't use the turkey pan with aluminum heads or manifold.
-Differential expansion-
(Check Edelbrock's or Trick Flow's sites for gasket recommendations.)
The point of it is to keep oil from cooking on the heated exhaust crossover,
not hot oil from heating the manifold.
And, YOU WON'T HAVE a heated exhaust crossover...
In all, I am glad you are going with the TFS Streets.
I know it doesn't fit your "Ford, another way" ideal.
But it will give you less headaches and a better margin in the end.
I think the heated spacer is another red herring.
By the time the coolant is up to temp the aluminum heads are going to be too.
I agree, the coolant would get there just a little bit faster. But it's the heat balancing/consistency and prevention of carb overheating that it really does help.

Heck, the 6,084# springs in my F-250 hop with only 220Hp.
The 9" bolt in third member lends itself very well to bolting on a torque arm. My favorite way to control axle wrap with leaf springs, doubles as driveline protection to.

Yes, I saw the pic and only skimmed your text.
I already Repped you for the temp stability thoughts, once I went back and really looked at your post.
The 9" torque arm is an interesting item I'm not too familiar with.
Most people would go to a 4-link and coilovers these days.
I know Gary wants to keep it as much 'Dad's Truck' as he can.
Ok guys, I was confused. I am using a turkey pan on Rusty w/an Eddy Performer manifold and cast iron heads and assumed I would with the Trick Flows and the same intake. But while you were typing I was calling TFS and they told me the same thing you did:
There's no need for the turkey pan since there's no exhaust heat in the intake manifold
A FelPro #1205 gasket will easily make up for the lack of the pan's thickness
The lack of exhaust heat won't be a problem at all with economy, although he did agree that running heated air in the air cleaner is the way to go.
And, I just had a thought about the heated intake air. While running the 105 degree ACTS gives up some total power potential, assuming outside air temp is cooler, it really is a moot point as the vacuum will drop at WOT such that the flappers will come fully open and allow only cool air in.
As for the torque arm, wouldn't that put a LOT of stress on that little bolt at the top of the 9"??? I just looked under Rusty and there's not much room under there. And then the front end of the arm would have to be anchored, which requires a cross member. I think the snubber is more practical, but will have to think about this.
And, I missed the edit with the carb spacer so had to go back and see what you two were talking about. Now I understand. We'll see if I need that, but will start w/o it and can add it in later if needed. Thanks!
In fact, I think a lot of things are going to be "if needed". Like a torque arm. But, I appreciate the input.
Gary,
It looks like the torque arm gets two bolts at the top and the two at the pinion flange too.
If it is rotating around the axle, the bottom is pushing much more than the top is in tension.
Now that I look a bit more closely I see you are right - as always. I'm thinking it pushing will be the main prevention from wrapping. Would you go all the way forward to the rear tranny crossmember with the arm?
I could fab something like that as it looks like it is angle and square tubing. Might be an interesting project.
Let's turn this conversation to ignition systems. I'm planning on just going with a rebuilt DS-II system as I'm pretty sure it is adequate to as high as I'll spin the 400. So today was looking at the dizzy that came off the $40 400 I bought - the one with three wire nuts on it. It has an ID tag showing D7AE 12127-BA. That's a bit too old for my parts catalog, although the catalog does have D8TE 12127-BA.
Anyway, I did a Google search for the D7 # and got a hit on
. A new, not rebuilt, unit for $19.38 and free shipping? And Amazon says it fits an 81 F250 w/the 400. Granted I don't need the dual vacuum advance so may be able to find another # without it, but it sure is cheap. And I have the adjustable Crane unit on Rusty that'll go right on this one, so what's wrong with this picture?
Is the $40 engine one DSII???
I think you'll get lots of arcing if you run that cap with a hot coil and wide plug gaps.
You have no other emissions stuff going into your engine.
Why would you need retard on closed throttle?
If Rusty's dizzy already has a Crane advance, swap the whole thing into Dad's Truck.
Those two little screws always strip if you run them in and out a few times.
ETA: (1) "Made in Taiwan"
(2) Will that cast iron gear work with the cam you're getting?
I wasn't suggesting I would run that cap. But I obviously didn't state that and should have. Sorry. I was only thinking of using that new housing, pickup, harness, etc. And I would run the later style adaptor and cap.
I could swap Dad's dizzy, which has a good vacuum advance, into Rusty and vice versa. But both of those units are well worn. And, while the $40 engine had a DS-II dizzy with side-play that appears to be minimal, the end-play is about 1/8". So, I could re-work any of them, but for $19 it doesn't seem worth it.
I don't know what gear the cam needs, but the gear could easily be swapped.
