[DeTomaso] Intake manifold tilt

[Doug Braun]

Ken,

    I modified my Edelbrock F351 (old version of Performer) manifold for a
level carburetor as follows using a Bridgeport mill:

1)  Remove the carb mounting studs and fill the stud holes with J-B Weld.
2)  Jig & clamp the manifold to the mill so its "S" shaped end rail gasket
surfaces are parallel to the mill table.
3)  Mill the minimum amount off the intake's carb mounting surface to remove
its angled surface.  Any machine shop can
     easily do this step for you.
4)  Drill new carb mounting stud holes (they end up being half in the J-B
Weld and Half in the aluminum.
5)  Insert heli-coils in the new stud holes for strength and a stainless
steel thread.
6)  Seal the bottom of one of the stud holes that MUST break through into
one of the runners with fuel proof epoxy.

While my method worked well, its was a lot of work and I can't say it's
necessary to go to all this trouble.  I just didn't
like the idea of the studs being at the wrong angle to mount the carb. I
also didn't want the look of an angled
spacer.  I like to keep things looking as stock looking as possible.

  Doug,

      Is the angle change small enough that the studs/bolts still line up
OK?

    Sean,

    Keeping a flat carb mounting surface (so the carb seals) is more
important
    than the angle of the surface being spot on level. But if you're a
stickler
    for exactness, the carb surface is "level" when it's milled parallel to
the
    front and rear "s" shaped bottom areas of the manifold that seal against
the
    front and rear "S" shaped rails of the engine block valley. If you set
the
    manifold on a mill's table indexed to these "S" shaped surfaces, the
    resulting milling will give you a level carb. Did mine this way and it
    definitely solved the stalling on hard braking downhill problem I had.

    My newly reborn Pantera has some carburetor issues. I think it's a
little
    tilted after I installed my injector bung festooned manifold. Does
anyone
    know how many degrees I should shave a carburetor spacer to get it level
    again? It looks like about 5 degrees, and the angle finder has it
somewhere
    between 4 and 6 degrees, but I thought there might be an accepted angle
for
    Panteras.

    Of course, I could work on getting the EFI working instead :)
