A friend has given me a Torker intake to use and when I install it on the engine I see it tilts the carb forward a fair amount. I understand they do this for a mustang as the engine tilts back to achieve drive line angles. As the engine was not in the car when I got it I can't judge if the engine sits level (I am assuming it does). If the engine does sit level I could see some possible drivability problems with the carb tilted forward that much. Any thoughts?? Thanks

You could have the carb base milled flat, or get a carb spacer and have it milled at an angle (how ever many degrees to make sit level)
I'm sure others will be able to help more then I.
Good Luck

Normally you could adjust float levels to compensate for the angle of the carb. Such a forward angle could cause flooding during hard braking. It will also cause a large tilt on the air cleaner. I would recommend milling the intake flat.

Moroso makes a 5 deg spacer that works great! I have one on my car with a Edelbrock Performer RPM air gap.

I bought mine from Summit Racing for like $35

I'm with you, mounting the carb at a nose down angle is not ideal. The Blue Thunder intake is available with a flat carb mount, designed specifically for our Panteras.

When automobile motors are mounted in some boats, they are mounted flat just as in the Pantera. I've seen the angle carby spacers Ron refers to in boat shops as well.

Although the angle is not ideal, when hot rodders raise the rear end of a car, or lower the front end, sometimes worse angles are encountered by the carby than what's encountered in the Pantera, and they run just fine. Many an owner has been running his Pantera with similar angles to the carby for more than 30 years.

I ride off road motorcycles. Carbys on our off-road motors encounter all sorts of extreme angles on a continuous basis, with seldom a hiccup.

I wouldn't consider optimizing the angle of the carby a waste of time, but I doubt you'll measure any benefits.

Was the original equipment intake manifold in the Pantera special for the car?
I thought that it was just a box stock iron 4v CJ Ford intake manifold?

When one adjusts the float levels in a Holley, the adjustments for special applications are made to maintain a static fuel level in the emulsion tubes and idle transfer slots.

As long as that is taken into account there should be no problem.

If you are using a Holley carb with fuel level sight plugs in the bowls, you may have to switch to Moroso type clear plugs and adjust the level higher then "normal" instructions would have.

This is true of the Ford 2-4v carb set ups that mount the carb backwards.

In that case the secondaries are adjusted higher then specs and the primaries lower. If you don't the primaries will flood at idle and the secondaries will run dry.

Thanks for the info. My concern is a sudden stop, carb flooding, engine stalling loosing brake assistance.
I did not know there was an angle plate available. I'm sure it will reduce the angle somewhat , maybe enough to make a difference during a severe brake application.

In my experience in autocross and open track events all cars equipped with a carb where the fuel bowl is in the front or the rear of the carb will stall under severve braking because the fuel is sloshing away from the idle circuit pick up.

Moroso does make fuel jet extensions to counter this but they are not a foolproof guaranty.

Some of the Holley carbs with racing applications are equipped with air vent extensions to reduce the amount of fuel spilled through the top of the carb. It doesn't eliminate it though.

The only way to prevent the staling that I know of is by going to fuel injection where there are no fuel bowls.

One of the nice things about the Weber 48ida set-ups is that they are much less susceptable to the fuel sloshing problems. It also makes them very responsive in high speed turns.

If you are milling an edelbrock torker 2760 flat then you are milling into the threaded hole for the vacuum connection and maybe also into the runners.
I would recommend a spacer instead.

Priced a plate to offset the angle and then priced a airgap intake for 2v head which will help torque and botton end (mistake). So guess what I did?? I ordered the manifold and plate as the airgap has a slight angle biult into it also. I hate myself
