Welcome. John Mummert has a rebuild kit for the 292 that is reasonable.

The stock 4 barrel iron intake is a good choice. Find one with the B suffix so it will fit the later carbs. A good choice is the Holley 1848 4 barrel. It is a stock replacement and is set up to match your acc linkage. Available at Holley new. Recommend going with a 5 blade fan, and pointless kit for your distributor. These are good trucks especially hard to find one without rusted out floors, fenders. Let us know how it is going.
