0320-d2j

Can someone tell me if the 320-d2j can support a constant speed prop?

Bill - I think from the doc at the link enclosed the answer is 'no'.

But I would suggest you check my understanding.

Perhaps an electric MT prop? I used that on the -9a I built, though I guess its not right on a -4!

Good luck.

I converted an 0320E2A to a C/S prop and this is an engine that is listed to have a solid Crank (but Mine was hollow), the crankcase was not supposed to have a tapped hole near the front end (mine had the hole with a pipe plug sealing it) and the accessory case was not supposed to have a pad for the governor (mine had a plate covering the hole). Lycoming, when asked about the feasibility of a prop change, said the engine should not be capable but, in production, they may not have the proper components handy and they use what they have which will work. Therefore, a person has to look to see what you have regardless what the specifications say. I was lucky and you may be as well. I must have about 75 hours on the new prop.

My RV-6 has a D2J. It has a governor pad, but it is not machined or drilled. I'm sure you could have a certified shop machine the case, but that involves a complete tear down of the engine.
