AMC Clutch / Primary Drive Options

Hello all,

Hope everyone is well. I am currently building a triton slimline special, which will eventually house a dominator engine once funds allow some Maney / Molnar engine parts. 

I have a dominator gearbox from a 1960 650SS, rebuilt by Dave Coates which has the RGM close ratio gear kit. 

I am looking for recommendations from anybody who has used either a commando style clutch and belt drive with a dominator box, or stuck with the dominator clutch with the kush rubbers and primary chain. 

My main goal here is to find a good solution that will not kill my gearbox for general fast road use. 

I absolutely do not want a primary case filled with oil. I am going for the road racer style, and want to have an open primary. 

If you were in my shoes would you run a dominator clutch with open chain, or a commando clutch without the kush rubbers and a belt drive?

Am I destined for gearbox ruin if I use a commando clutch and get rid of the kush to run a belt drive?

Why does nobody make a dominator clutch with a belt drive kit? Seems like a gap in the market to me...

I understand that I will need to use a sleeve or change mainshaft for commando clutch.

Any advice would be much appreciated.

Cheers
