I have not done such a conversion. But others have done so on the AFB & AVS carbs. Follow there leed on drilling out the fuel passages for greater volume. You have to have more fuel for the lower btu return on E85. IIRC, again, lol, I think it is 30% more fuel. Do check that amount!

On jets and rods, the factory, MP or Carter, has never offered a kit to convert to E85 or alcohol use. Metering rods and jets are available from IIRC, the carb shop. This is really a “google question” to search for.
Demonsizzler, who uses to be here and was a master at these carbs used to drill out the air bleed(s) and install Holley air bleeds to further along the tuneable aspect of the TQ. I really don’t know his tricks. So I can’t provide any tips along the modification line.
I can tell you that I have bent AFB rods 3/4 of an inch shorter, and clipped the ends off, to fit the TQ. Since there are many AFB rod choices available, you should be in good shape there.
I have only fiddled around with the TQ. When there good, there great.
