It does not look like TR6, but it is a duel unit that uses the TR3 box and seems to protrude further into the firewall box.  This proves that it is possible to build something not too far outside of the standard TR3 setup and if it works for Jeff, it's well tested and performs as needed.

If need be to get it moving, you can also use the starter motor in first gear (ignition off) for the first couple revolutions (it’s really not as hard on the starter as it sounds), put the clutch in, and let your “mules” kick the best they can.

With a new engine, I almost always spend a few hours on a local chassis dyno - seat the rings, set the timing, check performance, play with carb jets, etc.  Way better than showing up at an event with adjustments not made or an engine that blows up on the first run.

Basically an engine/trans pull, as swapping a flywheel with the engine still in the car and the transmission out just sounds painful.
