With the room that it has above the barrel will it be fitted with a down draft carb straight above the inlet or a long manifold and a carb. The down draft would be better for performance and less work.

so long as your happy, but slugs in my opinion and experience should be hollow, similar wall thickness to the tube your joining, and ideally about 1.5 times the diameter in length

some nice work going on there, I look forward to seeing more of it
