Hi Tommy,

    Can't remember is your engine plugs up or automobile orientation?  I
have the tubes running about 1" from the block at the closest point (where
that flat area juts out about mid way up the center housing).

If  auto orientation,   the dia of largest tube is 1 5/8" so that places it
2 5/8" out from the block.  So if you have 3 - 4 inches clearance it might
just work, although the throttle body would stick up above the 2 5/8"
whatever distance it is long, unless you ran a hose from a throttle body
mounted elsewhere - to the plenum. Actually, a version could have the tubes
fed from the end, in other words create one with a flat plate on the top
rather than the side of the casting and then you could mount a throttle body
without any difficulty. Hummmm.

  I can't wait to get it airborne.  It saves 12 lbs off my old arrangement
and it the start of a serious effort to get my aircraft lightened up a bit.
I am shortening the tubes an inch or so over my old one to get my torque
peak from around 5300 rpm to around 5800 rpm for better cruise BSFC.
