Yes you do if you use that carbide bit. I'm telling you go to the autoparts store and get a can of it and you'll be done in no time. If you have a friend to help out then every minute or 2 have them spray a little on the bit as you are shaving down the edges and what how fast it goes. Make DAMN sure you have protective goggles on because you do not want those shavings in your eyes.
And yes, the butterflies would be kinda ovalish since you can't remove any material on the divider.
If all goes well, that V6 oughta be nice and healthy.

machine shop guys claims it's harder to do than it sounds. I personally don't see how you can screw up making a pair of 2.125" round pieces of metal?
but it's safe to say i'm looking at doing a 57-54-57 venturi'd overbore.
don’t think you want to get into this. To do it right, you have to mount the “throttle plate” on a jig that is cut to the correct angle of idle. You start with a jig cut at the correct angle and bolt a plate on to it and then turn it down on the lathe. You then need to polish the machined ends. The throttle bushings can have no air leakage, etc….

if it's possible get a template made and color the edges with some black paint or magic marker that will transfer to the T.B., press the template around the openings and just cut to that point. Make sure it's something that will stay on even with the penetrating oil being sprayed on it.

If nothing else, i'll get one of those hole saws that you put in a drill press, but the centering bit is removable. I'd like to think they make a 2.25" one, which should be close to perfect? Then just run it out of thickish sheet metal.

yea, I plan to sharpie the measurements on the outside, and do the venturi bit by bit till the new blades fit. Assuming, of course, i can make new blades.

i dont know if they make those bits for metal...they're usually for wood. me being a metal smith...i dont see it that hard to make discs at all, i do it all the time. get yourself a compass if you can...take your ruler, measure out the radius you need and slowly rotate the compass...draws it out. simple as pie. lol then cut it out with snips or something and slowly sand or file it down to perfect size. done sir done.
