'71 Duster 318 4speed to 383 4 speed?

What would I need to go from a 318 to a 383 in my '71 Duster 4 speed car?
I know I would need a big block bellhousing. Would my 10.5 -23 spline clutch setup from the 318 work?

I also assume that since the 383 was mated to a 727 that I would need to drill out the end of the crank for the pilot bearing.

Is there a specific type of exhaust manifolds that are ideal to fit in the Duster's engine bay? Which oil pan is needed?
