Take a look at this and satisfy my curiosity

Won't you loose on the low end with a single plane manifold. I even got a dual plane on my 5.0 (airgap intake, 650cfm carb). And I wouldn't switch to a single unless I put a 347 stroker kit or when I put my 393 engine into the stang...

The side with the little freeze plug is alright, it's the other side, next to where the egr bolts to.

Ahh yes I was looking at it backwards. Ohwell good learning experience. Im sure it could still be done if you just made it narrow enough.

Well anyway I still might give it a try and see what happens. I picked up my roller bearings today.

Just need a chance to machine the TB to recieve them.
