If you are looking for the cost of admission with new stuff - then take a look at these parts:
Speedway Motors - small pattern carb adapter p/n 1351935B (about $20.00 plus shipping)
Cardone - rebuilt Y-block distributor for a 292 CID 1964 F100 pickup - p/n 30-2808 (about $99.00 plus shipping) doesn't include cap
For the distributor - you might find a used part for less from one of the guys on the forum.
Then go looking for a carb ............ My favorite recommendation is the 390 cfm Holley but many will work.
