There are ring and pinion set made for the torque tube rear ends with a big variety of ratio's. Just use your computer search engine to look up those vendors. I have two 216's. One a splasher, the other converted to full pressure. I use a 3:55 in the '47 splasher and a 3:07 with a T-5 in the other. I have a Tach in each and both are at about 2900 at 65 MPH. My gear sets are from Getz Gears. I have a buddy here locally with a '41 coupe with a 216 with dual carbs, hi-lift rocker arms (1.6) and headers. He turns 3,600 RPMS all day long and it is holding together fine.

Somebody’s pulling your leg.
There is not and never shall be another aftermarket ring and pinion alternative other than the 3:55 set for GM torque tube rear ends period. In comparison the stock 4:11 ring gear has over 3/8”of material from the root of the tooth at the outside diameter and on the upgrade this distance is reduced to less than 1/8”. There is simply no where else to go as the ring gear teeth would need to be cut right into the carrier so it’s just not physically possible. If Patrick Dykes could have picked up the phone and ordered a batch of 2:73 + - torque tube gearsets he would have done it by now and I laugh thinking how many times he must have heard that one.
On the HAMB a clever guy showed off his adaptation of a Jeep T-5 to a Furd torque tube rear and was asked about a Chevrolet solution and had no interest nor do I as the column shift 3 speed suits me fine but this is where I would investigate.
