Foxy Green Foxbody Build

Full vs proper should be a little more specific.

Mine is full.

Proper is 1/2 that amount.

My axle tubes are so full I'm surprised fluid isn't coming out of the vent

I hear ya, full doesn't always mean proper........... I have that fill cap up towards the top of the rear and yeah, if I actually kept putting fluid in there until it came out of there I can't imagine how much lube would come out of the vent!
 
extra un-sprung weight to keep the tire patches consistent while allowing the shocks to work with chassis roll :whistle: :pass:
 
Gale Banks did some testing on deferential gear lube drag/better lubrication and had some fixes for it but I do not remember what that was.
 
For the record.

I called 2 carburetor companies today. Before telling them I'm having issues, I asked what size carburetor they recommend on my combo.

Both of them. BOTH OF THEM. Said 750.

Sometimes you can't listen to internet experts when choosing parts.

What did the experts say to get?
Hard to have best of both words for street manners and 1/4 mile wot performance. I went with wot performance and will tolerate it's street ability, lol.
 
850 bare minimum or 950.

Reasons I heard were a 427 is going to have so much low end torque it won't matter, dual plane is a piece of shit, small 210 heads...

Well the fuckin thing barely breaks the tires loose and pulls like a ford suv.

So what do you blame first.

Heads
Cam
Intake
Carburetor

I needed a stump puller from 1800 to 5500rpm and instead it seems it's more like the window is 3500 to 5500 and an absolute dog otherwise. Stock 302 pulled harder, but the carb certainly still isn't calibrated correctly

I may be way out in left field here, but when I think "stump puller" it's big block gasser or Diesel for low rpm torque.

My reasoning on this...
A 427 cu inch small block and a 427 cu inch big block, the big block to me is going to feel like
it could pull a house down, rotational mass/ rotational inertia maybe is the term?
Tell me if I am way wrong on this. (y)

Somebody who says "950" needs to say what type of 950.
The original Holley configuration (750 body, 850 plate) seems like the perfect street carb for a 427.

Anyway, an 850 with annulars seems like it should work OK in a 427.

It's a big cam for low RPM use but again, you should enough displacement to make it work.

Your best bet might be to see if you can borrow a working 750 VS and see what happens.

For real? That's a huge let down.
Have you driven it in the 4,000-6,500 range and found it to have a lot of power there?

Something doesn't seem right. Mine was only a 409, heads with 240cc intake runner, single plane, both unported, too much duration, 268/276 @ .050 and it had a flat tq line of 500 ft/lbs and had loads of bottom end in a fox with 4.10's and a manual.
Your combo would usually make more tq than what I did. You have a smaller head, less duration iirc but same overlap of 50° with a longer stroke and more cubes.
Where did the cam end up dialing in at ?
 
I haven't spent much time above 4500 because, street car.

Cam
.638/.622
243/255
113lsa installed 111

Couldn't tell you what lobe shape they used but I believe they don't like the XE lobes, so probably LST

Biggest difference I'm seeing between ours is mine was 108 in at 104ish and higher compression but..... even the same lift, .636, lol.
