Likely 383 swap-parts advice requested

I'm doing a 400/727/3.23/1971 Duster now. Same boat as you, a slow moving project.
I went with the Schumacher swap kit and torque strap. The headers are A body headmen headers. Done with instructions from BBD.com.

So far, the parts in use now are a electric choke TQ, Holley's Street Dominator, MP distributor fired by a Summit racing box. A summit aluminum rad is also there, BUT it doesn't allow the stock viscous fan enuff room. No solution as of yet. But again, it may not stay.
I'll be looking into a Paxton or equal later on.
Cam size will be smallish as not to NEED a converter change… for now.
